“…The selectivity of GAD synthesis was higher than that of DHA due to the higher affinity for adsorption of terminal alcohol groups on the photocatalyst surface compared to secondary alcohols. 44 Recently, a p-n heterojunction consisting of Bi 2 O 3 NPs on TiO 2 nanorod arrayson PEC oxidation of glycerol to DHA resulted in a selectivity of 75.4%. Moreover, even at a relatively high glycerol conversion rate of 50%, selectivity of DHA remained at approximately 65% over Bi 2 O 3 /TiO 2 .…”

“…[41][42][43][44] Among them, replacing OER with glycerol oxidation reaction has drawn considerable attention. [45][46][47][48][49] In this concept, we highlight the recent advances in PEC glycerol oxidation to synthesize high value-added products at room temperature, including DHA, glyceraldehyde, glyceric acid, glycolic acid, formic acid and carbon monoxide (Table 1), and also explain the reaction mechanism. Moreover, the current challenges and future prospects for the PEC glycerol selective oxidation system are presented.…”

The catalytic oxidation of glycerol, a surplus byproduct of biodiesel, has received increasing attention due to the popular applications of its oxidation products, such as aldehydes, ketones, and carboxylates. Photoelectrochemical (PEC) methods provide a clean and sustainable pathway for glycerol oxidation and upgrading. However, selective oxidation of glycerol is a challenge due to its complex oxidation path, where the cleavage of C–O or C–C bonds at different positions can lead to a variety of products. This concept aims to describe the recent advances in PEC selective glycerol oxidation for the preparation of multiple high value‐added products, and discuss the reaction mechanism and selective production strategies in detail. Finally, the remaining challenges and future prospects for the PEC glycerol oxidation system are presented.

“…The absence of reactive oxygen species (ROS) also enabled the formation and retention of multicarbon products (Figure S26). − Figure c displays the reported selectivities for catalyst-free TiO 2 photooxidation of glycerol to GLD, ,,− and obviously, the TNT-50 photoanode occupies the highest point. Adequate regulation of the microenvironment was undoubtedly involved in reversing the selectivities of the photoanodes under unrestricted conditions, which provides valuable ideas for designing more effective catalysts for biomass oxidation in the future.…”

The glycerol oxidation reaction (GOR) run with photoelectrochemical cells (PECs) is one of the most promising ways to upgrade biomass because it is thermodynamically favorable, while irreversible overoxidation leads to unsatisfactory product selectivities. Herein, a tunable one-dimensional nanoconfined environment was introduced into the GOR process, which accelerated mass transfer of glycerol via the microscale fluid effect and changed the main oxidation product from formic acid (FA) to glyceraldehyde (GLD), which led to retention of the heavier multicarbon products. The rate of glycerol diffusion in the nanochannels increased by a factor of 4.92 with decreasing inner diameters. The main product from the PEC-selective oxidation of glycerol changed from the C1 product FA to the C3 product GLD with a great selectivity of 60.7%. This work provides a favorable approach for inhibiting further oxidation of multicarbon products and illustrates the importance of microenvironmental regulation in biomass oxidation.
