Mechanism of Hydrogen Spillover on Metal-Doped Carbon Materials: Surface Carboxylic Groups Are Key

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(9), P. 7111 - 7126

Published: April 23, 2024

Hydrogen spillover (H-spillover) is the surface migration of activated hydrogen atoms from a metallic particle on which they are generated onto support. The phenomenon has been widely studied because its implication in storage and catalytic reactions involving hydrogen. Its existence carbon materials well established, but questions remain regarding mechanism involvement oxygen groups. In this study, we combined experimental work with chemical modeling to study mechanisms H-spillover representative system, including material presenting basal prismatic surfaces: oxidized nanotubes doped Pd. results, supported by those modeling, show that carboxylic acid groups key species, allowing take place. can also combination phenol facilitate H-spillover. If concentration these too low, then does not operate, except case addition water, serves as shuttle for protons. This leads deeper understanding long-debated issue provides insight into designing systems enhanced properties.

Bubbles Management for Enhanced Catalytic Water Splitting Performance

Catalysts, Journal Year: 2024, Volume and Issue: 14(4), P. 254 - 254

Published: April 11, 2024

Water splitting is widely acknowledged as an efficient method for hydrogen production. In recent years, significant research efforts have been directed towards developing cost-effective electrocatalysts. However, the management of bubbles formed on electrode surface during electrolysis has largely overlooked. These can impede active sites, resulting in decreased catalytic performance and stability, especially at high current densities. Consequently, this impediment affects energy conversion efficiency water splitting. To address these challenges, review offers a comprehensive overview advanced strategies aimed improving mitigating obstructive effects primarily involve utilization experimental apparatus to observe bubble-growth behavior, encompassing nucleation, growth, detachment stages. Moreover, examines factors influencing bubble formation, considering both mechanical behaviors internal factors. Additionally, design water-splitting catalysts discussed, focusing modifying electrode-surface characteristics. Finally, concludes by summarizing potential large-scale industrial production identifying future directions achieving
