Heteroatom-doping had been demonstrated to effectively improve the capacitive energy storage of hard carbon in potassium ion batteries (KIBs). However, the external defects introduced during doping process are responsible to alter the microstructure of carbon host. But there is a scarcity of systematic in-depth understanding the comprehensive effects of defects and heteroatoms in hard carbon for K storage performance. Herein, a series of porous carbon microspheres in different defects level and ...

Ga-La5Ti2Cu0.9Ag0.1O7S5 (Ga-LTCA), an oxysulfide photocatalyst, can act as a hydrogen evolution photocatalyst in Z-scheme water splitting systems in conjunction with an oxygen evolution photocatalyst (OEP) under visible light irradiation up to 700 nm. However, the overall efficiency is strongly limited by the low activity of Ga-LTCA. The present work demonstrates a drastic improvement in the H2 evolution activity of Ga-LTCA after loading small Rh cocatalyst particles exhibiting uniform dispersio...

Promoting charge separation is still the main challenge in the rational design of photocatalysts for visible light photocatalytic reduction of CO2. Based on the unique advantages of the Eu3+ single atom and the Type-II heterojunction in the field of photocatalytic reduction, a Eu3+ single atom doped CdS/InVO4 Type-II heterojunction was successfully constructed through the combination of hydrothermal and in situ synthesis. The prepared CdS/InVO4:Eu3+ single atom composite material has excellent p...

Bismuth-based coordination polymers (CPs) have recently attracted attention as catalyst precursors for the electrocatalytic CO2 reduction reaction (eCO2RR). We present a comparative study by investigating six bismuth-based compounds in-depth to elucidate the correlation between their structures and their catalytic CO2-to-formate conversion. Thereby, we identify structural indicators of the pristine CPs resulting in optimized catalytic performance, paving the way for future design of CP derived c...

Electrolyte cost and long-term durability are the two most challenging obstacles to the practical utilization of redox-active organics in aqueous redox flow batteries. Starting from potentially inexpensive 1,8-dihydroxyanthraquinone (1,8-DHAQ), we developed a one-pot, green, and scalable approach to synthesize a highly water-soluble and potentially low-cost anthraquinone 1,8-dihydroxy-2,7-dicarboxymethyl-9,10-anthraquinone (DCDHAQ). The demonstrated volumetric capacity of DCDHAQ in 1 M KOH is 40...

Developing effective bifunctional catalysts for the oxygen reduction and evolution reaction (ORR/OER) is essential for accelerating the cathode efficiency of Zn–air batteries. Herein, atomically dispersed Ni single atoms are supported by sub-10 nm Pd nanocrystals embedded in N-doped carbon frameworks (Ni SAs-Pd@NC), in an effort to achieve superior bifunctional activity in both the ORR and OER. The key synthetic point depends on the protection mechanism of 1-naphthylamine, which could provide a ...

Polymers are widely used in modern electronics thermal management systems, due to their light weight, electrical insulation, and low cost. However, the low intrinsic thermal conductivity (TC) of polymer restricts its applications. The low intrinsic TC is due to the entanglement of polymer chains and defects such as voids which act as phonon scattering sites. Regulating the structure of polymers is an effective way to improve the intrinsic TC. Generally, traditional approaches can achieve only a ...

Flower-ball-like ZnIn2S4@hollow dodecahedral polyoxometalate (K3PW12O40)@flower-shell-like ZnIn2S4/Ag2S yolk@shell dual Z-scheme superstructure tandem heterojunction nanoreactors are fabricated through a two-step hydrothermal method combined with a cation exchange strategy. Hollow dodecahedral K3PW12O40 acts as a bridge to form the special yolk@shell dual Z-scheme superstructure tandem heterojunction between two types of ZnIn2S4. Due to the encapsulation and confinement effects of the nanoreacto...

Owing to the 100% atom utilization and the high activity, single atom catalysts (SACs) toward photocatalytic oxidation (PCO) represent a promising technology. However, its practical industrial application has been still limited by the complex synthesis methods of the catalyst. Herein, a simple two-step electrochemical approach was developed to synthesize an atomically dispersed Au-loaded WO3/TiO2 nanotubes array for volatile organic compounds (VOCs) oxidation. Au atoms were proved to be anchored...

In the context of carbon neutrality, significant progress has been made in the exploration of advanced porous organic polymers (POPs) as a promising and emerging platform for heterogeneous CO2 catalysis in the past few decades owing to their structural designability and functional diversity, high thermal and chemical stability, and ability to accelerate the mass-transfer rate. Inspired by natural biological systems, incorporation of metalloporphyrin moieties into the porous skeletons via covalen...
