Controlled Synthesis of Graphdiyne-Based Multiscale Catalysts for Energy Conversion.

Graphdiyne (GDY) science is a new and rapidly developing interdisciplinary field that touches on various areas of chemistry, physics, information science, material science, life science, environmental science, and so on. The rapid development of GDY science is part of the trend in development of carbon materials. GDY, with its unique structure and fascinating properties, has greatly promoted fundamental research toward practical applications of carbon materials.

Constructing CO-immune water dissociation sites around Pt to achieve stable operation in high CO concentration environment.

The serious problem of carbon monoxide (CO) poisoning on the surface of Pt-based catalysts has long constrained the commercialization of proton exchange membrane fuel cells (PEMFCs). Regeneration of Pt sites by maintaining CO scavenging ability through precise construction of the surface and interface structure of the catalyst is the key to obtaining high-performance CO-resistant catalysts. Here, we used molybdenum carbide (MoC) as the support for Pt and introduced Ru single atoms (SA-Ru) at the Pt-MoC interface to jointly decrease the CO adsorption strength on Pt.

Locking the lattice oxygen in RuO to stabilize highly active Ru sites in acidic water oxidation.

Ruthenium dioxide is presently the most active catalyst for the oxygen evolution reaction (OER) in acidic media but suffers from severe Ru dissolution resulting from the high covalency of Ru-O bonds triggering lattice oxygen oxidation. Here, we report an interstitial silicon-doping strategy to stabilize the highly active Ru sites of RuO while suppressing lattice oxygen oxidation. The representative Si-RuO-0.

Strengthening Pt/WO interfacial interactions to increase the CO tolerance of Pt for hydrogen oxidation reaction.

Here, the modulation of the Pt electronic structure by the formation of an amorphous WO overlayer on Pt nanoparticles is proposed. The resulting Pt/WO@NC electrode shows exceptional CO oxidation potential (0.24 V .

Manipulating the surface composition of Pt-Ru bimetallic nanoparticles to control the methanol oxidation reaction pathway.

The rational manipulation of reaction intermediates is crucial for achieving high-performance heterogeneous catalysis. Herein, using in situ Fourier transform infrared-diffuse reflection (FTIR) analysis, we report that the methanol oxidation reaction (MOR) intermediates can be controlled by precisely tuning the location and content of Ru on the Pt-Ru alloy surface.

Conducting Polymers and Their Applications in Diabetes Management.

Advances in conducting polymers (CPs) have promoted the development of diabetic monitoring and treatment, which is of great significance in human healthcare and modern medicine. CPs are special polymers with physical and electrochemical features resembling metals, inorganic semiconductors and non-conducting polymers. To improve and extend their properties, the fabrication of CPs and CP composites has attracted intensive attention in recent decades.
