Synergistic Effects of Co-Doping on Photocatalytic
Development of conversion of biomass derivatives in combination with utilization of solar energy by photocatalysts is a promising alternative strategy for biorefineries. The photocatalytic reaction could convert glucose to a mixture of value-added chemicals under UV irradiation. Modifications of titanium dioxide (TiO2) nanoparticles by metal or metalloid (i.e. B and Ag) and nonmetal (i.e. N
