Anthropogenic nitrate pollution has an adverse impact on the environment and human health. As part of a sustainable nitrate management strategy, electrochemical denitrification is studied as an innovative strategy for nutrients recycling and recovering. It is, however, challenging to selectively electro‐reduce nitrate with low‐concentration for ammonia. Herein, the photo‐deposition of size‐defined...
As a core component, the catalyst layer (CL) is widely used in fuel cell, metal‐air battery, and other energy conversion devices. Herein, a highly efficient method for CL preparation via fast current‐driven synthesis followed by pyrolysis is proposed. Compared with previously reported fabrication procedures of zeolite imidazolate frameworks (ZIF)‐based CLs, this method directly deposits the ZIF precursor...
The activatable imaging technique in the second near‐infrared window (NIR‐II) utilizes the stimulation of cancer‐associated biomarkers for specific imaging to guide precise NIR‐II photothermal therapy. However, most activatable nanoprobes with single‐source stimulation are insufficient in providing comprehensive information regarding the tumor, severely restricting the therapeutic optimization, especially...
The organic–inorganic hybrid perovskite solar cells present a rapid improvement on power conversion efficiency from 3.8% to 25.5% in the past decades. Owing to the tuneable bandgaps, low‐cost, and ease of fabrication, perovskites become ideal candidate materials for fabricating tandem solar cells, especially for efficient and high‐voltage monolithic two‐terminal devices. In this review, an overview...
Lithium–sulfur (Li–S) battery is one of the most promising next‐generation rechargeable batteries. Lots of fundamental research has been done for the problems during cycling like capacity fading and columbic efficiency reducing owing to severe diffusion and migration of polysulfide intermediates. In the early stage, a wide variety of carbon materials are used as host materials for sulfur to enhance...
