Hydrogen peroxide (H2O2) is a highly value‐added and environmental‐friendly chemical with various applications. The production of H2O2 by electrocatalytic 2e− oxygen reduction reaction (ORR) has emerged as a promising alternative to the energy‐intensive anthraquinone process. High selectivity Catalysts combining with superior activity are critical for the efficient electrosynthesis of H2O2. Earth‐abundant...
The self‐healing ability of superhydrophobic surfaces in air has attracted tremendous additions in recent years. Once the superhydrophobic surface is damaged underwater, water seeps into gaps among micro/nano structures. The air film diffuses into water and eventually disappears during immersion without actively replenishing the gas, which results in the impossible of self‐healing. Here, an underwater...
Electrochemical nitrogen reduction reaction (NRR) to ammonia (NH3) using renewable electricity provides a promising approach towards carbon neutral. What's more, it has been regarded as the most promising alternative to the traditional Haber‐Bosch route in current context of developing sustainable technologies. The development of a class of highly efficient electrocatalysts with high selectivity and...
Glucose monitoring is essential to evaluate the degree of glucose metabolism disorders. The enzymatic determination has been the most widely used method in glucose detection because of its high efficiency, accuracy, and sensitivity. Noble metal nanomaterials (NMs, i.e., Au, Ag, Pt, and Pd), inheriting their excellent electronic, optical, and enzyme‐like properties, are classified as noble metal nanozymes...
The electrochemical nitrogen reduction reaction (NRR) is a promising strategy of nitrogen fixation into ammonia under ambient conditions. However, the development of electrochemical NRR is highly bottlenecked by the expensive noble metal catalysts. As a representative 2D nonmetallic material, black phosphorus (BP) has the valence electron structure similar to nitrogen, which can effectively adsorb...
Inspired by the stomata of plant leaves, Naien Shi, Yue Lin, Min Han, and co‐workers fabricate 2D Cu‐N‐C nanodisks with stomata‐like interconnected hierarchical porous topology by etching Cu‐tetrapyridylporphyrin (TPyP)‐metal–organic frameworks carbonization product (Cu@Cu‐N‐C) in article number 1902410. Such nanodiscs manifest superior oxygen reduction reaction performance, outperforming Cu@Cu‐N‐C,...
Metal,N‐codoped carbon (M‐N‐C) nanostructures are promising electrocatalysts toward oxygen reduction reaction (ORR) or other gas‐involved energy electrocatalysis. Further creating pores into M‐N‐C nanostructures can increase their surface area, fully expose the active sites, and improve mass transfer and electrocatalytic efficiency. Nonetheless, it remains a challenge to fabricate M‐N‐C nanomaterials...
Silicon carbide (SiC) is one of the most important third‐generation semiconductor materials. However, the chemical robustness of SiC makes it very difficult to process, and only very limited methods are available to fabricate nanostructures on SiC. In this work, a hybrid anodic and metal‐assisted chemical etching (MACE) method is proposed to fabricate SiC nanowires based on wet etching approaches...
In article number 1801809, Liangti Qu and co‐workers establish large‐scale series‐connected asymmetrical micro‐supercapacitors (AMSCs) on a flexible substrate through laser direct writing technology. The integrated AMSC array with the high voltage output exhibits a feasibility for practical application by combination with energy conversion (e.g., solar cells) and energy consumption devices.
The micro‐supercapacitors are of great value for portable, flexible, and integrated electronic equipments. Here, the large‐scale and integrated asymmetrical micro‐supercapacitor (AMSC) array is fabricated in virtue of the laser direct writing and electrodeposition technology. The AMSC shows the ideal flexibility, high areal specific capacitance (21.8 mF cm−2), and good rate capability. Moreover, its...
The emergence of multidrug resistant bacterium threatens to unravel global healthcare systems, built up over centuries of medical research and development. Current antibiotics have little resistance against this onslaught as bacterium strains can quickly evolve effective defense mechanisms. Fortunately, alternative therapies exist and, at the forefront of research lays the photodynamic inhibition...
