Special Issue Information

Dear Colleagues,

By selectively tuning the activation barrier of a specific reaction pathway, via preferentially enriching kinetically relevant species under working conditions, a catalyst alters the kinetics of a chemical reaction without changing the intrinsic thermodynamic equilibrium between materials. So far, metal (oxide), semiconductor, and even insulator-based materials are found in various forms in heterogeneous catalysis and photocatalysis, where thermal- or photo-energy drives the turnover of a reaction and transform energy into chemical bonds. Large-scale production of fine chemicals and commodities has been dominantly catalyzed by heterogeneous catalysis in the chemical industry and will continue to do so in the forthcoming future. On the other hand, the creation of all living organisms has ultimately been driven by sunlight via various forms of photocatalyzed reactions. The mimicking of photocatalytic activities in nature is often termed artificial photosynthesis. This Special Issue focusing on “Heterogeneous Catalysis and Photocatalysis in Materials” calls for the submission of manuscripts from the general fields of heterogeneous catalysis and photocatalysis.

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. Materials is an international peer-reviewed open access semimonthly 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 2600 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.

In recent years, metallic nanoparticle (NP)–two-dimensional material hybrids have been widely used for photocatalysis and photoreduction. Here, we introduce a femtosecond laser reduction approach that relies on the repetitive ablation of recast layers by usi–ng temporally shaped pulses to achieve the fast fabrication of metallic NP–two-dimensional material hybrids. We selectively deposited silver-reduced graphene oxide (Ag–rGO) hybrids on different substrates under various fabrication conditions. The deposition of the hybrids was attributed to the redistribution of the cooling ejected plume after multiple radiation pulses and the exchange of carriers with ejected plume ions containing activated species such as small carbon clusters and H2O. The proposed one-step in situ fabrication method is a competitive fabrication process that eliminates the additive separation process and exhibits morphological controllability. The Ag–rGO hybrids demonstrate considerable potential for chemomolecular and biomolecular detection because the surface-enhanced Raman scattering signal of the enhancement factor reached 4.04 × 108.
