Built‐In Electric Field in 2D/2D LDH/Antimonene Heterostructure to Induce Stable β‐NiOOH at Ultralow Potential for Cost‐Effective Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
In this paper, a built‐in electric field (BEF) strategy is proposed to fabricate NiFe‐LDH/antimonene heterostructure as bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The formed BEF generates a local potential that reduces the potential for the formation of β‐NiOOH, thereby enabling ultra‐low ...

Principle of Earth materials: A historical perspective of thermodynamics of the Earth

open access: yes地质科技通报
Earth is a combination of material and energy. The evolution of Earth and planets is a history of the transfer of matter and energy. Materials science is codified into physics and chemistry, while mathematics is the language that describes the law of ...

Defect‐Free Block Copolymer‐Based Distributed Bragg Reflector for Optimized Light Harvesting in BiVO4 Photoanodes

open access: yesAdvanced Functional Materials, EarlyView.
A solution‐processed distributed Bragg reflector (DBR) film, integrated via block copolymer (BCP) self‐assembly, enhances photon recycling in BiVO4 photoanodes for improved photoelectrochemical (PEC) performance. By tuning lamellar structures using lactic acid and cross‐linking density, the DBR film optimally shifts working wavelengths, boosting ...
