Transformation of biomass into value-added chemicals and fuels is considered an upcycling process that is beneficial to resource utilization. In this study, we used a photoelectrochemical (PEC) approach for selective oxidation of propane-1,2,3-triol to dihydroxyacetone (DHA) with high efficiency and ...

Oxygen vacancies (OVs) are one of the most critical factors that enhance the electrical and catalytic characteristics of metal oxide-based photo-electrodes. In this work, a simple procedure was applied to prepare reduced TiO 2 nanotube arrays (NTAs) (TiO 2−x) via a one-step reduction method using Na ...

In this study, we report a facile one-step chemical method to synthesize reduced titanium dioxide (TiO$_2$) nanotube arrays (NTAs) with point defects. Treatment with NaBH$_4$ introduces oxygen vacancies (OVs) in the TiO$_2$ lattice. Chemical analysis and optical studies indicate that the OV density ...
