Recently, there are significant progresses in the growth of organic-inorganic lead halide perovskite single crystals, however, due to their susceptible nucleation and growth mechanisms and solvent requirements, the efficient and generalized growth for these single crystals is still challenging. Here we report the work towards this target with a polymer-controlled nucleation process for the highly efficient growth of large-size high-quality simple ternary, mixed-cations and mixed-halide perovskite single crystals. Among them, the carrier lifetime of FAPbBr3 single crystals is largely improved to 10199 ns. Mixed MA/FAPbBr3 single crystals are synthesized. The crucial point in this process is suggested to be an appropriate coordinative interaction between polymer oxygen groups and Pb2+, greatly decreasing the nuclei concentrations by as much as 4 orders of magnitudes. This polymer-controlled route would help optimizing the solution-based OIHPs crystal growth and promoting applications of perovskite single crystals.
A paired electrochemical refinery toward cathodic nitrate reduction reaction (NO3RR) and anodic glycerol oxidation reaction (GOR) driven by renewable electricity could generate high value-added ammonia and formic acid, simultaneously. However,...
Harnessing abundant renewable resources and pollutants on a large scale to address environmental challenges while providing sustainable freshwater is a significant endeavor. In this study, we present the design of fully functional solar vaporization devices (SVD) based on organic‐inorganic hybrid nanocomposites (CCMs‐x). These devices exhibit efficient photothermal properties that facilitate multi‐targeted interfacial reactions, enabling simultaneous catalysis of sewage and desalination. The localized interfacial heating generated by the photothermal effect of CCMs‐x triggers surface‐dominated catalysis and steam generation. The CCMs‐x SVD achieves a solar water‐vapor generation rate of 1.41 kg m−2 h−1 (90.8%), and it achieves over 95% removal of pollutants within 60 min under one‐sun for practical application. The exceptional photothermal conversion rate of wastewater for environmental remediation and water capture is attributed to customized microenvironments within the system. The integrated parallel reaction system in SVD ensures it a real‐life application in multiple scenarios such as municipal, medical wastewater and brine containing high concentrations. Additionally, the SVD exhibits long‐term durability, antifouling functionality toward complex ionic contaminants. This study not only demonstrates a One‐Stone‐Two‐Birds strategy for large scale directly producing the potable water from polluted seawater, but also open up to exciting possibilities of parallel production of energy and water resources.This article is protected by copyright.
