Article Abstract
Currently, Pt-based nanomaterials with tailorable shapes, structures, and morphologies are the most popular electrocatalysts for oxygen reduction reaction, which is a significant cathode reaction in fuel cells for renewable energy applications. We have successfully synthesized mesoporous core-shell Au@PtNi ternary metallic nanoparticles through a one-pot reduction method for cathodic materials used as oxygen reduction reaction catalysts. The as-synthesized nanoparticles exhibited superior catalytic activities and long-term stabilities compared with mesoporous core-shell Au@Pt nanoparticles and commercial Pt/C. The unique mesoporous core-shell structures as well as the alloy shells enable the enhanced electrochemical oxygen reduction reaction performances of the Pt-based materials via the electronic effect and geometric effect, holding great promise in fuel cell application.

Introduction: Conventional pesticide formulations have been widely used to boost agricultural productivity, but their weak foliar adhesion and instability under UV light during spraying lead to low utilization rates and potential environmental and health hazards. To counter these challenges, the development of nanoformulations represents a pivotal strategy. These advanced formulations are designed to enhance the efficacy of active ingredients (AIs) and reduce ecological impacts, thereby addressing the need for sustainable agricultural development.

Selective conversion of organic pollutants in wastewater into value-added chemicals is a promising strategy for sustainable water management. Electrochemical processes offer attractive features of precise control over reaction pathway to achieve desired products, however, the traditional anode-mediated processes still face challenges of over-oxidation by the inevitably formed of hydroxyl radical (HO). Herein, we proposed a new cathode-mediated approach for selective conversion of phenol to p-benzoquinone (p-BQ) through peroxymonosulfate (PMS) activation.

This study introduces the synthesis and characterization of advanced silica core-shell nanostructures, with an emphasis on the innovative Si-ACS (Silica Acorn Core-Shell) design and its modified counterparts. Employing the classic Stöber method, SiCore particles were first produced, followed by the creation of the acorn-like Si-ACS structures. A key aspect of this research is the exploration of the effects of CTAB and TEOS concentrations on the morphology and properties of the silica shells.

The ability to tailor surface area, porosity, and morphologies has driven extensive research into the synthesis of metal-organic frameworks derived carbons and their applications in energy storage. This study presents the development of three-dimensional hierarchically porous carbon derived from polystyrene and small-sized zeolitic imidazolate framework-8 (ZIF-8) particles. Incorporating nanometer-sized ZIF-8 particles forms a core-shell structure in the pre-carbonization stage, transforming into a porous carbon material with a range of pores from micro to macropores after carbonization.
