Conjugated polymers (CPs) have recently gained increasing attention as photocatalysts for sunlight‐driven hydrogen evolution. However, they suffer from insufficient electron output sites and poor solubility in organic solvents, severely limiting their photocatalytic performance and applicability. Herein, solution‐processable all–acceptor (A1–A2)‐type CPs based on sulfide‐oxidized ladder‐type heteroarene...
Lithium metal batteries (LMBs) are promising for next‐generation high‐energy‐density batteries owing to the highest specific capacity and the lowest potential of Li metal anode. However, the LMBs are normally confronted with drastic capacity fading under extremely cold conditions mainly due to the freezing issue and sluggish Li+ desolvation process in commercial ethylene carbonate (EC)‐based electrolyte...
Recently, single‐atom catalysts are attracting much attention in sensor field due to their remarkable peroxidase‐ or oxidase‐like activities. Herein, peroxidase‐like FeCoZn triple‐atom catalyst supported on S‐ and N‐doped carbon derived from ZIF‐8 (FeCoZn‐TAC/SNC) serves as a proof‐of‐concept nanozyme. In this paper, a dual‐channel nanozyme‐based colorimetric sensor array is presented for identifying...
Electrochemical reduction of oxygen plays a critical role in emerging electrochemical energy technologies. Multiple electron transfer processes, involving adsorption and activation of O2 and generation of protons from water molecules, cause the sluggish kinetics of the oxygen reduction reaction (ORR). Herein, a double‐active‐site catalyst of Fe3C nanoparticles coupled to paulownia wood‐derived N‐doped...
Real‐time observation of the electrochemical mechanistic behavior at various scales offers new insightful information to improve the performance of lithium‐ion batteries (LIBs). As complementary to the X‐ray‐based techniques and electron microscopy‐based methodologies, neutron scattering provides additional and unique advantages in materials research, owing to the different interactions with atomic...
As one of the most efficient electrochemical energy storage devices, the energy density of lithium‐ion batteries (LIBs) has been extensively improved in the past several decades. However, with increased energy density, the safety risk of LIBs becomes higher too. The frequently occurred battery accidents worldwide remind us that safeness is a crucial requirement for LIBs, especially in environments...
