Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

Advanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.

2D Multivariate‐Metal‐Organic Frameworks (2D‐M2OF) for High Yield Ammonia Synthesis from Nitrate

Advanced Energy Materials, EarlyView.
2D multivariate‐metal‐organic frameworks (2D‐M2OFs) enable efficient ammonia electrosynthesis from nitrates under ambient conditions. Incorporating Co, Ni, Mn, and Ag into BHT‐based 2D‐MOF creates a synergistic catalytic architecture that enhances nitrate reduction via surface hydrogen co‐adsorption.
