Selective Photoelectrocatalytic Glycerol Oxidation to Dihydroxyacetone via Enhanced Middle Hydroxyl Adsorption over aBi2O3-Incorporated Catalyst

Lan Luo et al.

Summary: This study reports a photoelectrocatalytic (PEC) glycerol oxidation method for the production of dihydroxyacetone (DHA) with enhanced selectivity. A heterogeneous photoanode consisting of Bi2O3 nanoparticles on TiO2 nanorod arrays was used, and the selectivity of DHA was increased. Experimental and theoretical studies revealed the interaction between the catalyst and glycerol, as well as the parallel pathways of the reaction. Furthermore, a self-powered PEC system was designed, achieving high productivity of DHA and H2.

Mediating the Oxidizing Capability of Surface-Bound Hydroxyl Radicals Produced by Photoelectrochemical Water Oxidation to Convert Glycerol into Dihydroxyacetone

Yang Liu et al.

Summary: In this study, a ternary photoanode material was developed for the selective oxidation of glycerol to 1,3-dihydroxyacetone. The photoanode showed high selectivity and kinetic response, with hydroxyl radicals generated by water oxidation playing a dominant role as active oxygen species. The oxidation product obtained mainly came from water. The role of different components in enhancing the selectivity and catalyzing the reaction was revealed through spectroscopic and computational studies.

Zhenao Gu et al.

Summary: The study demonstrates a microfluidic photoelectrochemical architecture with enhanced efficiency and selectivity for solar-chemical synthesis. The efficient charge separation leads to a 3-fold enhancement in product yield and a typical reaction selectivity of 85%, which is significantly higher than conventional methods. Integration of the microfluidic photoanode with an oxygen reduction cathode results in a self-sustained photocatalytic fuel cell with remarkably high open circuit voltage and short-circuit current.

Electrochemical Oxidation of Glycerol to Dihydroxyacetone in Borate Buffer: Enhancing Activity and Selectivity by Borate-Polyol Coordination Chemistry

Xin Huang et al.

Summary: Selective electrochemical oxidation of glycerol can improve the environmental impact and economic feasibility of biodiesel production, while generating valuable C-3 chemicals. Coordination of borate ions with polyol molecules enhances the activity and selectivity of electrocatalysts, leading to high production of C-3 chemicals. This strategy could potentially be applied to a wide range of biomass-derived sugars and polyols for producing value-added chemicals on low-cost non-noble metal electrocatalysts.

Photoelectrochemistry-driven selective hydroxyl oxidation of polyols: Synergy between Au nanoparticles and C3N4 nanosheets

Yongrong Sun et al.

Summary: A new photoelectrochemical strategy using Au/C3N4 catalyst has been proposed to enhance the selectivity and kinetics of middle hydroxyl oxidation in glycerol molecules. By introducing illumination and utilizing C3N4, high selectivity to dihydroxyacetone and unprecedented turnover frequency were achieved. The synergy of electronic interaction, localized surface plasmon resonance effect, and photogenerated carriers dual injection plays a key role in enhancing the selectivity and kinetics of the oxidation process.

Current developments and future trends in photocatalytic glycerol valorization: process analysis

M. R. Karimi Estahbanati et al.

Summary: In recent years, rapid advances in biodiesel technologies have led to a glycerol glut in the market, resulting in a significant drop in its price. The development of glycerol valorization techniques, particularly the photocatalytic process, has attracted considerable attention for its potential to integrate solar energy with glycerol conversion at ambient conditions. Through analysis of glycerol photoreforming and photo-oxidation mechanisms, as well as evaluation of empirical models and synthesis parameters, researchers aim to address both challenges and opportunities in this forefront technology.
