A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

Ordered Nanostructural Engineering of Cathode Catalyst Layer With High Mass Transport Efficiency for High‐Performance Ultra‐Low Pt Loading Proton Exchange Membrane Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An ordered cathode catalyst layer with efficient mass transport capability was developed based on the ALD of Pt onto VACNTs for high‐performance ultra‐low Pt loading PEMFC. The order‐structured cathode catalyst layer (CCL) has been considered the most promising solution to construct low‐cost proton exchange membrane fuel cells (PEMFCs) with an ultra ...

China: the upcoming global gas giant

open access: yes, 2016
The global natural gas market has been unusual among commodities in that it has not had a China story over the last ten years. The market has seen significant volatility, due in part to its shallow liquidity pool and some big fundamental swings – Qatari LNG trains and post-Fukushima Japan being the stand-out ones.

Rational Design of CdS QDs/CeO2 Nanocube S‐Scheme Heterojunctions for Highly Efficient C2H4 Scavenging in Fresh Produce Preservation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel S‐scheme heterojunction of CdS quantum dots on CeO2 nanocubes was designed to enhance charge separation and oxygen activation for efficient photocatalytic ethylene removal. The optimized composite achieved complete C2H4 degradation within 4 min under low‐intensity visible light, with a rate constant of 1.72 min−1. Mechanistic analysis confirmed
