Glyceraldehyde production by photocatalytic oxidation of glycerol on WO3-based materials
(Elsevier, 2021)Valorization of glycerol into high added-value products by photocatalysis can not only create good economic benefits, but also cater to the global low-carbon and energy-saving environmental protection needs. In this study ... -
Glycerol and Catalysis by Waste/Low-Cost Materials—A Review
(MDPI, 2022)The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, for example. The most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain ... -
Glycerol photoreforming for photocatalytic hydrogen production on binary and ternary Pt-g-C3N4-TiO2 systems: a comparative study
(Elsevier, 2024)Photocatalytic hydrogen production using two sacrificial agents (triethanolamine and glycerol) was conducted on several binary (Pt/TiO2 and Pt/g-C3N4) and ternary systems (Pt on a heterojunction between TiO2 and g-C3N4 ... -
