Biochar Meets Single‐Atom: A Catalyst for Efficient Utilization in Environmental Protection Applications and Energy Conversion

Small, Journal Year: 2024, Volume and Issue: 20(44)

Published: July 10, 2024

Single-atom catalysts (SACs), combining the advantages of multiphase and homogeneous catalysis, have been increasingly investigated in various catalytic applications. Carbon-based SACs attracted much attention due to their large specific surface area, high porosity, particular electronic structure, excellent stability. As a cheap readily available carbon material, biochar has begun be used as an alternative nanotubes, graphene, other such expensive matrices prepare SACs. However, review biochar-based for environmental pollutant removal energy conversion storage is lacking. This focuses on strategies synthesizing SACs, pre-treatment organisms with metal salts, insertion elements into biochar, or pyrolysis metal-rich biomass, which are more simplistic ways Meanwhile, this paper attempts 1) demonstrate applications remediation based advanced oxidation technology electrocatalysis; 2) reveal mechanism different systems; 3) discuss stability SACs; 4) present future developments challenges regarding

In–Sb Covalent Bonds over Sb₂Se₃/In₂Se₃ Heterojunction for Enhanced Photoelectrochemical Water Splitting

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(21), P. 10068 - 10078

Published: May 17, 2024

Antimony selenide is a promising P-type photocatalyst, but it has large number of deep energy level defects, leading to severe carrier recombination. The construction heterojunction common way resolve this problem. However, the conventional system inevitably introduces interface defects. Herein, we employ in situ synthesis epitaxially grow In2Se3 nanosheets on Sb2Se3 nanorods and form In–Sb covalent interfacial bonds. This petal-shaped heterostructure reduced defects enhanced efficiency separation transport. In work, photocurrent density proposed Sb2Se3/In2Se3 photocathode 0.485 mA cm–2 at 0 VRHE, which 30 times higher than that pristine prominent long-term stability for 24 h without obvious decay. results reveal synergy bidirectional built-in electric field constructed between solid bonds together build high-efficiency transport channel photogenerated carriers display photoelectrochemical (PEC) water-splitting performance. work provides efficient guidance reducing via
