Special Issue Information

Dear Colleagues,

The use of metal nanoparticles (MNPs) in catalysis has experienced growing interest in recent years. This revolution arises from the special features of MNPs as catalysts, which unify the advantages of both homogeneous and heterogeneous catalysts. MNPs exhibit the characteristics of high stability and recyclability of heterogeneous catalysts but present a higher surface area (i.e., larger number of surface active sites). All of these elements make MNPs ideal catalysts for many catalytic processes. Therefore, the incorporation of recent advances, new reactions, and novel catalysts in this research area is of great interest for the scientific community.

This Special Issue of Catalysts centered on “Advances in Metal Nanoparticle Catalysis” will focus on all areas of current interest to metal nanoparticles in catalysis, including ligand-stabilized MNPs, atomically precise clusters, supported/encapsulated MNPs, subnanometer metal clusters, self-assembly of MNPs, ligand and support effects, surface studies, catalysis in ionic liquids, theoretical studies, laboratory and industrial applications and electrocatalysis, among others. Full papers, communications, reviews, and concepts on any topic related to the application of MNPs in catalysis are more than welcome and will be considered for publication.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Catalysts is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Hydrogen peroxide (H2O2) is an important industrial chemical that is widely applied in many areas. The direct synthesis of H2O2 from H2 and O2 has proved to be a green and economic pathway. Pd-based bimetallic catalysts, due to their superior catalytic performances in this reaction, have attracted intensive attention. Herein, Tetrakis(hydroxymethyl)phosphonium chloride (THPC) was adopted as the protective ligand to immobilize Pd-Au alloy nanoparticles onto activated carbon (AC). The varied Pd/Au molar ratios demonstrated homogeneously distributed Pd-Au nanoalloys with average particle sizes ranging from 3.51 to 5.75 nm. The optimal ratio was observed over the Pd3Au1/AC-THPC catalyst with a maximum H2O2 productivity of 165 mol/(kgPd·h) and selectivity of 82.3% under ambient pressure. The relationship between the electronic structure and catalytic activity indicated Pd0 was the active site, while the presence of Au inhibited H2O2 degradation rate. This research could help in the design efficient bimetallic catalysts for the direct synthesis of H2O2. Full article
