23:T45c,Abstract The realization of carbon neutralization requires further development of high‐performance supercapacitors, while their wider applications are limited by serious self‐discharge. This work proposes a conjugately configured supercapacitor, as well as the strategy for optimizing the structure of active materials specifically for such supercapacitor. The conjugated supercapacitor consists of pairs of prelithiated T‐Nb 2 O 5 @C and forms a Li x Nb 2 O 5 @C versus Li 2 − x Nb 2 O 5 @C configuration. We demonstrate that the elegant control of the coated carbon shell has a significant effect on the self‐discharge behavior. An optimized annealing temperature of 300°C is beneficial for reducing the elemental impurity while not introducing microregional phase impurity, thus leading the best resistance towards self‐discharge. When the conjugated supercapacitor is charged to an initial voltage of 1.0 V, the voltage could retain for more than 3000 min before dropping to 0.5 V. This work is expected to provide general guidance for optimizing the active materials for conjugated supercapacitors.24:T49f,As known, mercury contamination is one of the current environmental issues due to the high toxicity of mercury. Corn bract (CB) is an agricultural by-product, and its final treatment is generally incineration that causes air pollution. In this study, a new type of high-efficiency biomass adsorbent (CB@MoS₂) for adsorption of Hg(ii) was obtained, and its morphology and structure were characterized with FT-IR, XRD, SEM and TEM. The results showed that when the pH value, Hg(ii) ion concentration and adsorption time were 4, 100 mg L^-1 and 120 min, the adsorption capacity and removal rate could reach 332.50 mg g^-1 and 99.75%. In addition, CB@MoS₂ had a good selectivity for Hg(ii) ions. The adsorption behavior followed pseudo-second-order kinetics, indicating that the adsorption of Hg(ii) ions by CB@MoS₂ was a chemical adsorption. After five adsorption-desorption experiments, it still possessed good adsorption performance and effective regeneration. In short, CB@MoS₂ has high efficiency and good reusability, and will become a candidate material for the treatment of mercury-containing industrial wastewater.25:T6e1,
