Abstract:
Metal-supported catalyst with high activity and relatively simple preparation method is given priority to industrial production. In this work, this study reported an easily accessible synthesis strategy to prepare Mott-Schottky-type N-doped carbon encapsulated metallic Co (Co@Np+gC) catalyst by high-temperature pyrolysis method in which carbon nitride (g-C3N4) and dopamine were used as support and nitrogen source. The prepared Co@Np+gC presented a Mott-Schottky effect; that is, a strong electronic interaction of metallic Co and N-doped carbon shell was constructed to lead to the generation of

Abstract:
At present, the selective hydrogenation of α, β-unsaturated aldehydes remains a challenge due to competition between unsaturated functional groups (C=C and C=O). In this study, N-doped carbon deposited on silica-supported nickel Mott–Schottky type catalysts (Ni/SiO2@NxC) was prepared for the selective hydrogenation of cinnamaldehyde (CAL) by using the respective hydrothermal method and high-temperature carbonization method. The prepared optimal Ni/SiO2@N7C catalyst achieved 98.9% conversion and 83.1% selectivity for 3-phenylpropionaldehyde (HCAL) in the selective hydrogenation reaction of CAL.

Abstract:
The two-electron water oxidation reaction (2e- WOR) has drawn growing attention as a potential method of producing hydrogen peroxide (H2O2) on-site through electrochemical water splitting. Despite ongoing efforts to identify more effective electrocatalysts for 2e- WOR, it remains a challenge to simultaneously achieve good activity, selectivity, and stability with a single catalyst material. In thermal catalysis, metal oxide supports have often been used to tune the catalytic properties of the supported metal catalysts. Inspired by this support effect, we experimentally and computationally expl

Abstract:
Electrochemical water splitting, composed of two half reactions: the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER), is under intensive research to the development of H2 fuels to replace fossil fuels. Since both reactions are sluggish, catalysts are usually required to boost them. The state-of-the-art catalysts for both reactions are based on noble metals, such as Pt-based catalysts for HER and Ir or Ru-based catalysts for OER. Unfortunately, the high price and scarcity of these noble metals suppress the widespread application of water splitting. Hence, it is imperat

Abstract:
The two-electron water oxidation reaction (WOR) has drawn recent attention as an efficient, simple method of producing on-site hydrogen peroxide through electrochemical water splitting. However, finding electrocatalysts with high activity and stability in the reaction’s harsh oxidizing environment is challenging. This is made especially difficult due to the competing four-electron and one-electron WOR, which necessitate a catalyst material with high selectivity towards the hydrogen peroxide production pathway. Here, we utilize metal/metal oxide coupling interactions to tune metal oxide catalys

The synthesized photocatalyst was characterized by X-ray diffraction, UV-vis diffuse reflectance, and photoluminescence, Mott-Schottky (MS) analysis and linear sweep voltammetry (LSV). The catalyst loadings were varied from 0.25 – 1.0 g/L and the optimum catalyst loading found to be 0.5 g/L. At the optimum loading, the conversion achieved was 83.7%.

Abstract:
Storing renewable energy into chemical bonds like hydrogen as a carbon-neutral energy carrier to deliver the energy demands is gaining attention. However, the popular hydrogen production route by water electrolysis involves sluggish half-cell reactions, namely, hydrogen and oxygen evolution reaction (HER and OER), urging the unequivocal development of electrocatalysts. Further, the employment of hydrogen in fuel cells involves a multielectron cathodic oxygen reduction reaction (ORR) that governs the overall efficiency of the fuel cells. Therefore, designing efficient alternatives to scarce and
