“…This manual procedure works fine for substrates with a small area but becomes challenging when large areas have to be coated. One example of using drop coating to prepare large-area photocatalytic carbon nitride films is shown by Schröder et al [7] Besides drop coating, there are many different methods available to prepare catalytic films, and one overview is given by Mehla et al [8] Within these different film producing methods, chemical vapor deposition DOI: 10.1002/ente.202100525…”

Following the example of photovoltaics, one approach to large‐scale photocatalytic hydrogen production is the irradiation of a correspondingly large catalyst area. Paper production is a process in which large areas can already be produced based on the main component: cellulose. Herein, the TiO2 photocatalyst modification PC500, which also uses platinum nanoparticles as a cocatalyst, is supported in two different ways using cellulose. On the one hand, the catalyst is fixed to the surface of a commercial filter paper and, on the other hand, a photocatalytic paper is produced. For comparison, the catalyst is immobilized by means of drop coating using Nafion and measured as a suspension. The cellulose‐stabilized films are active and hydrogen production is comparable with the activity obtained from the drop‐coating method. The experiments show that the aggregation behavior of cellulose can be used to produce photocatalytically active films. The preparation is easy and can be applied to different kinds of (photo)catalysts. Although the films are very active, their stability during reaction due to swelling and hydrogen production must be further improved.

“…The advantage of such a strategy is that, in contrast to the post-synthetic deposition of nanoparticles that are dispersed in solution, nanostructures that are well bonded to the substrate and evenly distributed will be present from the first step of the processing. The synthesis of new composite materials (proposed in our paper in the form of thin films) responds to part of the demand for the functionalization of novel materials and surfaces [ 55 , 56 ].…”

Microstructure and Optical Properties of Nanostructural Thin Films Fabricated through Oxidation of Au–Sn Intermetallic Compounds

et al. 2021

AuSn and AuSn2 thin films (5 nm) were used as precursors during the formation of semiconducting metal oxide nanostructures on a silicon substrate. The nanoparticles were produced in the processes of annealing and oxidation of gold–tin intermetallic compounds under ultra-high vacuum conditions. The formation process and morphology of a mixture of SnO2 and Au@SnOx (the core–shell structure) nanoparticles or Au nanocrystalites were carefully examined by means of spectroscopic ellipsometry (SE), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) combined with energy-dispersive X-ray spectroscopy (EDX). The annealing and oxidation of the thin film of the AuSn intermetallic compound led to the formation of uniformly distributed structures with a size of ∼20–30 nm. All of the synthesized nanoparticles exhibited a strong absorption band at 520–530 nm, which is typical for pure metallic or metal oxide systems.

“…The catalyst on the surface of microscale‐based reactors can be coated by several techniques, e.g., washcoating (WC), electrophoretic deposition (EPD), chemical vapor deposition (CVD), and physical vapor deposition (PVD) 18–20. In literature, WC using suspension and sol‐gel solutions has been generally employed 19, 20.…”

Pd/TiO₂ Coated in a Microscale‐Based Reactor by Electrophoretic Deposition for Biohydrogenated Diesel Production

et al. 2021

Electrophoretic deposition (EPD) was applied for the coating of a Pd/TiO2 catalyst for the production of biohydrogenated diesel (BHD) in a microscale‐based reactor. The coating of TiO2 using EPD was investigated under various operating conditions. The Pd/TiO2 catalysts prepared by EPD were compared with the samples obtained by the conventional washcoating (WC) technique. The optimum EPD condition giving a high degree of adhesion was determined, using Tiron and Pluronic F127 as the additives. The coated catalysts were tested for their catalytic activity. By comparing with Pd/TiO2(WC), Pd/TiO2(EPD) catalysts exhibited a higher catalytic performance which could be explained by their uniformity, high amount of Ti3+ species, and oxygen vacancies.
