Enhanced Photoelectrochemical Water Splitting Using Bismuth/Bismuth Selenide Nanocomposites

open access: yesChemistry – An Asian Journal, Volume 20, Issue 6, March 17, 2025.
Bismuth/Bismuth Selenide (Bi/Bi₂Se₃) nanocomposites exhibit enhanced photoelectrochemical (PEC) water splitting performance due to optimized energy band alignment and efficient charge separation. The figure illustrates the impact of synthesis temperature on bandgap tuning, leading to improved photocatalytic activity and hydrogen evolution.

Microbial Electrosynthesis for Sustainable Polyhydroxybutyrate Production from CO2 Using Bismuth Nanoparticles

open access: yesChemElectroChem, EarlyView.
Electrochemical CO2 reduction using a Bi‐based electrode generates formate as the sole carbon source for Cupriavidus necator to synthesize polyhydroxybutyrate (PHB). Two configurations are evaluated: the integrated system, performing fermentation in the same reactor post‐electrolysis, while the drop‐in system decouples both steps.
