Antimony (Sb), a toxic metalloid, has serious negative effects on human health and its pollution has become a global environmental problem. Bio-reduction of Sb(V) is an effective Sb-removal approach. This work, for the first time, demonstrates the feasibility of autotrophic Sb(V) bio-reduction...

Herein, amorphous catalysts were employed to investigate the catalytic ozonation system, revealing the degradation mechanism and influencing factors (Cu/Mn ratio, O3 concentration, temperature, and humidity) for toluene catalytic ozonation. Cu0.2MnOx exhibited the highest toluene oxidized (~92%...

Naphthalimide-based molecules, namely NEN and NTA, were designed and utilized as versatile cathode interlayers in organic solar cells (OSCs). Compared with one-armed NA previously reported and two-armed NEN, the NTA with a three-armed molecular structure exhibits more clearly the...

In quantum-dot light-emitting diodes (QLEDs), poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt(4,4’-(N-(4-butylphenyl))] (TFB) has been one of the most widely used hole-transport layer (HTL) materials. However, for solution-processed especially ink-jet printed QLEDs, TFB normally suffers from low...

The inherent limitations of semiconductors include low carrier concentrations and the non-directional utilization of internal carriers, which exhibit sluggish photocatalyst-mediated redox activities. Here, a novel high-performance Na-bridged photocatalyst with nitrogen vacancies (WNCN) was...

Adjustment of electronic structure in carbon skeleton has a major impact on the performance of carbon material for oxygen reduction reaction (ORR). Decreasing work function of carbon skeleton is one of the significant research branches for the development of carbonaceous catalysts. Herein,...

In this study, microporous nitrogen-doped nanocarbons from the carbonization of ZIF-8 (ZCN) was prepared as an efficient metal-free catalyst to improve sulfamethoxazole (SMX) degradation in Fe(III)/H 2 O 2 process. The SMX degradation ratio was increased from 20% to 100% with the addition of ZCN...

Uranium extraction from seawater has attracted increasing attentions for nuclear raw material to support the sustainable development of nuclear power plants. However, it is still a grand challenge to overcome the high salinity background and ultra-low uranyl concentration. Herein, we...

Generation of reactive radicals via photocatalytic peroxymonosulfate (PMS) is restricted by the sluggish kinetics of PMS decompositon and lack of electron transfer channel. Herein, we firstly prepared rare earth oxide functionalized carbon nitride (5-ScO-CN) by simple in-situ one-step...

Nitrous oxide (N 2 O) production and consumption occur concomitantly in the soil and their accurate quantification as the gas diffuses in situ under high background concentration of atmospheric dinitrogen remains largely elusive. This study designed an analytical and reliable approach for...
