Replacing the oxygen evolution reaction (OER) in photoelectrocatalytic (PEC) water splitting with glycerol oxidation (GOR) not only enhances hydrogen production but also generates high-value byproducts. In this study, we developed a ternary photoanode, Co-LDH/Bi2O3/TiO2, by loading particulate Bi2O3 and linear Co-LDH onto TiO2 nanorod for conversion production. The characterization results confirm formation of coupled interfaces between TiO2, which improves visible light utilization promotes type II heterojunctions, resulting significant suppression electron–hole recombination an improvement PEC performance. Fourier transform infrared (FT-IR) spectroscopy revealed that Co-LDH/Bi2O3/TiO2 photoanode exhibited stronger adsorption intermediate hydroxyl group more effective desorption DHA compared to binary photoanodes (Co-LDH/TiO2 Bi2O3/TiO2), high-selectivity DHA. Mechanistic studies density function theory calculations have shown Co-LDH/TiO2 oxidizes mainly through hole oxidation, Bi2O3/TiO2 radical (•OH) oxidation. Therefore, constructed (Co-LDH/Bi2O3/TiO2) dual heterojunction converts pathways •OH This work demonstrates promising strategy developing high-performance systems production, leveraging synergistic effects multisemiconductor heterojunctions multiple pathways, offering potential practical applications.

Abstract Conversion of glycerol to added‐value products is desirable due its surplus during biodiesel synthesis. TiO 2 has been the most explored catalyst. We performed a systematic study adsorption on anatase (101), (001), and rutile (110) at Density Functional Theory level. found several modes these surfaces, with (101) being less reactive one, leading energies between −0.8 −0.4 eV, all adsorptions molecular in nature. On contrary, (001) surface, both dissociative modes, ranging from −4 −1 eV undergoing severe surface reconstructions some cases. Rutile also shows adsorptions, but it than (001). Surfaces oxygen vacancies affects adsorbed states energies. The electronic structure analysis reveals that mainly band gap material not individual contributions valence conduction band. Bader charge strong are associated large transfer while weak involve low transfer.
