Abstract:

This manuscript provides a perspective on research work related to the catalysis in the immiscible liquid-liquid system. Three catalytic concepts, i.e., phase-transfer catalysis (PTC), triphase catalysis (TPC), and phase-boundary catalysis (PBC), are presented as well as their use for the design of a better catalytic system. This perspective emphasizes based on the SWO (Strengths, Weaknesses, and Opportunities) analysis of PTC, TPC, and PBC and advances concept uses for future directions of research in this area.

Abstract:

Efficient lipase catalysis requires sufficient oil–water interface engineered through structural design. Inspired by the architectural features of fabrics, a novel lipase-membrane catalytic system with interwoven polyacrylic acid (PAA) gel fibers and polyvinyl pyrrolidone (PVP) gel fibers was developed in this study by using double-needle electrospinning and gelation. It has been demonstrated that PAA/PVP hybrid gel fiber membranes (HGFMs) have a high swelling capacity for both water and oil phases, which created numerous discontinuous oil–water contact surface units in limited space of HGFMs,

Abstract:

The physicochemical properties of active components play a key role in enhancing catalytic performance. In multi-component catalysts, different components offer a wide range of structural possibilities and catalytic potential. However, determining the role of specific components in enhancing efficiency may be blurry. This study synthetized a range of catalysts with various metal compositions on their external surfaces to investigate their catalytic activity on NH3-SCR. The V/CeMn/Ti catalysts exhibited exceptional catalytic efficiency and strong tolerance to SO2 during the SCR process. In the

With the rapid development of industrialization, more and more organic pollutants are entering the water environment, rendering the treatment of organic pollutants a key issue in protecting it. Therefore, finding a convenient and effective method for degrading organic pollutants in water is of great importance. Triboelectrification is known as the process of charge transfer during the friction process. It is always accompanied by the energy level transition of electrons or holes, making it a potential method for catalytic degradation, which we refer to as triboelectrification catalysis. In thi

The residual cationic catalytic activity of the deactivated Ib system is due to presence of AlBr3. In contrast to TiCl3, the deactivated Ib system and the model system TiBr3 + AlBr3 are not activated by the addition of EtAlCl2 in the presence of butadiene: the highly active benzenetitanium(II) system is re-constituted only after reduction of TiBr3 with Et3Al followed by the addition

The methods of thermal analysis – thermogravimetry, differential thermal analysis – were used to study the catalytic system phosphor-molybdenum heteropoly acid–aluminum oxide.

On the surface of ƞ-Al2O3, phosphomolybdic acid is destroyed by interaction with strong Lewis’s acid sites of the carrier, while on γ-Al2O3 it retains the individuality, probably due to multipoint adsorption on weak Bronsted and Lewis acid sites of the oxide

Abstract:

N2 fixation into NH3 is one of the main processes in the chemical industry. Plasma catalysis is among the environmentally friendly alternatives to the industrial energy-intensive Haber-Bosch process. However, many questions remain open, such as the applicability of the conventional catalytic knowledge to plasma. In this work, we studied the performance of Al2O3-supported Fe, Ru, Co and Cu catalysts in plasma-catalytic NH3 synthesis in a DBD reactor. We investigated the effects of different active metals, and different ratios of the feed gas components, on the concentration and production rate

Abstract:

Ytterbium perfluorooctanesulfonate [Yb(OPf)3] catalyses the highly efficient synthesis of acylals from aldehydes and acetic anhydride in a fluorous biphase system (FBS) composed of toluene and perfluorodecalin. The fluorous phase containing the fluorous catalyst is easily separated and can be reused several times without significant loss of catalytic activity.Key words: acylals, ytterbium perfluorooctanesulfonate, fluorous biphasic catalysis.

Abstract:

Human production and living processes emit excessive VOCs into the atmosphere, posing significant threats to both human health and the environment. The photothermal catalytic oxidation process is an organic combination of photocatalysis and thermocatalysis. Utilizing photothermal catalytic degradation of VOCs can achieve better catalytic activity at lower temperatures, resulting in more rapid and thorough degradation of these compounds. Photothermal catalysis has been increasingly applied in the treatment of atmospheric VOCs due to its many advantages. A brief introduction on the three modes o

Abstract:

AbstractComplexity of tumor and its microenvironment as obstacles often restrict traditional tumor therapies. Enzyme/nanozyme‐mediated catalytic therapy has been emerged, but the efficacy of single catalytic therapy is still moderate. Inspired by the concepts of catalytic and synergetic therapy, an enzyme‐nanozyme cascade catalysis (ENCAT)‐enhanced tumor therapy is developed. First, metal–organic framework (MOF) PCN222‐Mn (PM) and glucose oxidase (GOx) are chosen as nanozyme and natural enzyme, respectively. Then two assembled together to form enzyme‐nanozyme complex PCN222‐Mn@GOx (PMG). To ac

Abstract:

Abstract Single-atom nanozymes (SAzymes) hold significant potential for tumor catalytic therapy, but their effectiveness is often compromised by low catalytic efficiency within tumor microenvironment. This efficiency is mainly influenced by key factors including hydrogen peroxide (H2O2) availability, acidity, and temperature. Simultaneous optimization of these key factors presents a significant challenge for tumor catalytic therapy. In this study, we developed a comprehensive strategy to refine single-atom catalytic kinetics for enhancing tumor catalytic therapy through dual-enzyme-driven casc
