ZnFe layered double hydroxide (LDH) was synthesized through which the [AuCl4](-) anions were directly intercalated in situ. Low temperature calcination converts the [AuCl4](-) intercalated LDH into an intimately mixed ZnFe metal oxides containing favorably dispersed Au nanoparticles. The unique microstructure exhibited substantially improved photocatalytic activity by more than 40 times compared to the baseline material intercalated with [CO3](2-). Such improvement is unprecedented among noble metal decorated photocatalyst materials and is elucidated based on the mechanisms of morphology evolution.

The atmospheric dicarboxylic acids (DCAs) have a significant impact on the climate and indirectly affect human health, making them important organic substances. PM bound DCAs were analysed for Jorhat, India, 2019. In addition to the temporal variability, seasonal variation throughout the year and the impact of varying meteorological factors on DCAs concentration have also been studied.

Practical Zn metal batteries have been hindered by several challenges, including Zn dendrite growth, undesirable side reactions, and unstable electrode/electrolyte interface. These issues are particularly more serious in low-concentration electrolytes. Herein, we design a Zn salt-mediated electrolyte with in situ ring-opening polymerization of the small molecule organic solvent.

A Scalable Calibration Method for Enhanced Accuracy in Dense Air Quality Monitoring Networks.
Environ Sci Technol
January 2025
Department of Chemistry, University of California Berkeley, Berkeley, California 94720, United States.
Deployment of large numbers of low capital cost sensors to increase the spatial density of air quality measurements enables applications that build on mapping air at neighborhood scales. Effective deployment requires not only low capital costs for observations but also a simultaneous reduction in labor costs. The Berkeley Environmental Air Quality and CO Network (BEACON) is a sensor network measuring O, CO, NO, and NO, particulate matter (PM), and CO at dozens of locations in cities where it is deployed.
