Carbon materials with unique sp2‐hybridization are extensively researched for catalytic applications due to their excellent conductivity and tunable physicochemical properties. However, the development of economic approaches to tailoring carbon materials into desired morphologies remains a challenge. Herein, a convenient “bottom‐up” strategy by pyrolysis of graphitic carbon nitride (g‐C3N4) (or other...
Electrochemical nitrate (NO3−) reduction to ammonia (NH3) offers a promising pathway to recover NO3− pollutants from industrial wastewater that can balance the nitrogen cycle and sustainable green NH3 production. However, the efficiency of electrocatalytic NO3− reduction to NH3 synthesis remains low for most of electrocatalysts due to complex reaction processes and severe hydrogen precipitation reaction...
Chemical communication via neurotransmitters is central to brain functions. Nevertheless, in vivo real‐time monitoring of neurotransmitters released in the brain, especially the electrochemically inactive molecules, remains a great challenge. In this work, a novel needle field‐effect transistor (FET) microsensor based on an acupuncture needle is proposed, which is demonstrated to be capable of real‐time...
Inorganic perovskite CsPbI2Br has advantages of excellent thermal stability and reasonable bandgap, which make it suitable for top layer of tandem solar cells. Nevertheless, solution‐processed all‐inorganic perovskites generally suffer from high‐density defects as well as significant tensile strain near underlayer/perovskite interface, both leading to compromised device efficiency and stability. In...
