Summary: A seeded method is developed to synthesize hollow PdSn intermetallic nanoparticles (NPs) with two different intermetallic phases, orthorhombic Pd2Sn and monoclinic Pd3Sn2. The obtained hollow orthorhombic Pd2Sn NPs exhibit excellent electrocatalytic performance towards glycerol oxidation reaction, surpassing solid orthorhombic Pd2Sn NPs, hollow monoclinic Pd3Sn2 NPs, and commercial Pd/C. The reaction mechanism using the hollow orthorhombic Pd2Sn catalyst is investigated, revealing its higher efficiency in cleaving the C-C bond compared to commercial Pd/C.

Summary: Electrocatalytic valorization of biomass derivatives is achieved through renewable energy sources, enabling a shift from centralized and energy-intensive processes to decentralized and low-temperature conversions. This approach offers an efficient, green, and additive-free strategy with tunable product selectivity. However, the scale-up application is hindered by challenges in conversion rates and selectivity. Further research on reaction mechanisms and development of efficient and selective electrocatalysts are needed to facilitate larger industrialization applications.

Summary: By fine-tuning the doping amount of phosphorus atoms, PdSnP nanocatalysts with different compositions were synthesized, and it was found that the doping of phosphorus atoms changed the composition and microstructure of PdSn nanocatalysts, forming amorphous and crystalline multiphase structures. This multiphase nanostructure with abundant interfacial defects effectively promoted the electrocatalytic oxidation efficiency of Pd atoms in small-molecule alcohols. Compared with undoped PdSn nanocatalysts and commercial Pd/C catalyst, the mass and specific activities of PdSn0.38P0.05 nanocatalysts in methanol oxidation reaction were significantly increased.

Summary: The reaction pathway of electrocatalytic glycerol oxidation can be controlled by incorporating amorphous antimony oxide on the surface of a Pt nanoparticle electrocatalyst, resulting in highly selective glycerol oxidation to dihydroxyacetone. This strategy not only improves the selectivity, stability, and electro-catalytic activity of the Pt electrocatalyst, but also promotes the glycerol conversion in the reaction.

Summary: By combining hydrogen evolution reaction (HER) with glycerol oxidation reaction (GOR), high-value chemicals can be obtained at the anode while saving energy to produce hydrogen. PtSA-NiCo LDHs/NF were synthesized by anchoring oxygen vacancies in NiCo LDHs with Pt to form Pt-O5 coordination. The study showed that LDHs act as active sites for catalyzing H-OH cleavage and promoting H2O dissociation during HER, while Pt single atoms serve as binding sites for H intermediates and accelerate proton-electron coupling to promote H2 release. In HER//GOR, a current density of 100 mA cm-2 and formate production at the anode can be achieved with a cell voltage of only 1.37 V. The work presents a novel green electrocatalytic synthesis strategy with synergistic coupling and dual promotion, enabling energy-saving hydrogen production and high-value chemicals at the anode.

Summary: Efficient nonprecious metal catalysts for the oxygen reduction reaction (ORR) in alkaline media are still a big challenge. In this study, a series of bimetallic oxide nanoparticle catalysts (SmFeOx@CN) with good morphology were successfully prepared using silica dioxide as an encapsulated template. The catalysts demonstrated comparable redox activity to commercial platinum-carbon catalysts and exhibited excellent stability, power, and energy densities, which can be attributed to the concerted effect of bimetallic oxide nanoparticles and the special electronic layer structure of rare earths.
