The effects of g-C3N4/biochar and g-C3N4 on bacterial community in riverbed sediment

Environmental Science and Pollution Research, 2022
Biochar had been widely used to improve the activity of photocatalysts, the biochar-based photocatalysts had more potential for environmental pollution remediation, but their effect on the sediment remained unknown. To understand these, the typical photocatalyst g-C3N4 was modified by biochar to develop g-C3N4/biochar with enhanced photocatalytic ...

Enhanced photocatalytic activity of ZnO/g-C3N4 composites by regulating stacked thickness of g-C3N4 nanosheets

Environmental Pollution, 2020
A self-assembly method was adopted to synthesize loading architecture of ZnO/g-C3N4 heterojunction composites by hybridization of g-C3N4 nanosheets and ZnO nanoparticles utilizing a refluxing method at a low temperature. More importantly, we provided a novel route to regulate the π-π restacking thickness of the g-C3N4 nanosheets among ZnO/g-C3N4 ...
