Platinum‐based atomically ordered alloys (i.e., intermetallic compounds) have distinct advantages over disordered solid solution counterparts in boosting the cathodic oxygen‐reduction reaction (ORR) in proton‐exchange‐membrane fuel cells. Nevertheless, the pivotal role of ordering degree of intermetallic catalysts in promoting ORR performance has been ignored heavily so far, probably owing to the...
Nanostructured carbon materials with high porosity and desired chemical functionalities are of immense interest because of their wide application potentials in catalysis, environment, and energy storage. Herein, a top‐down templating strategy is presented for the facile synthesis of functional porous carbons, based on the direct carbonization of diverse organic precursors with commercially available...
The rational design of catalytically active sites in porous materials is essential in electrocatalysis. Herein, atomically dispersed Fe‐Nx sites supported by hierarchically porous carbon membranes are designed to electrocatalyze the hydrazine oxidation reaction (HzOR), one of the key techniques in electrochemical nitrogen transformation. The high intrinsic catalytic activity of the Fe‐Nx single‐atom...
In article number 2002203, Tian Sheng, Shu‐Hui Sun, Jiayin Yuan, and co‐workers propose and verify atomically dispersed pyrrole‐type Fe‐N4 sites supported on hierarchically porous carbon membranes as real active sites for the electrochemical hydrazine oxidation reaction (HzOR), which will open up the future exploration of the metal‐Nx catalysts for HzOR in fuel cells and beyond.
Direct covalent functionalization of large‐area single‐layer hexagonal boron nitride (hBN) with various polymer brushes under mild conditions is presented. The photopolymerization of vinyl monomers results in the formation of thick and homogeneous (micropatterned, gradient) polymer brushes covalently bound to hBN. The brush layer mechanically and chemically stabilizes the material and allows facile...
In article number 1805228, Ihsan Amin, Tao Zhang, Rainer Jordan, and co‐workers present the direct covalent functionalization of hexagonal boron nitride (hBN) with polymer brushes under mild conditions. Photopolymerization results demonstrate the formation of thick and homogeneous (micropatterned, graded) polymer brushes covalently bound to hBN. The brush layer mechanically and chemically stabilizes...
This work reveals the intrinsic carrier transport behavior of 2D organolead halide perovskites based on phase‐pure homologous (n = 1, 2, and 3) Ruddelsden–Popper perovskite (RPP) (BA)2(MA)n−1PbnI3n+1 single crystals. The 2D perovskite field effect transistors with high‐quality exfoliated 2D perovskite bulk crystals are fabricated, and characteristic output and transfer curves are measured from individual...
Nanostructured carbon aerogels with outstanding physicochemical properties have exhibited great application potentials in widespread fields and therefore attracted extensive attentions recently. It is still a challenge so far to develop flexible and economical routes to fabricate high‐performance nanocarbon aerogels, preferably based on renewable resources. Here, ultralight and multifunctional reduced...
It is urgent to develop new kinds of low‐cost and high‐performance nonprecious metal (NPM) catalysts as alternatives to Pt‐based catalysts for oxygen reduction reaction (ORR) in fuel cells and metal–air batteries, which have been proved to be efficient to meet the challenge of increase of global energy demand and CO2 emissions. Here, an economical and sustainable method is developed for the synthesis...
