We fabricated plastic-supported Pt/N–TiO₂ (PNT) photocatalyst films from waste plastic <em>via</em> hot pressing.

When the temperature was not high enough, the polymer did not melt completely, leading to uneven surfaces and poor photocatalyst dispersion. Excessive pressure caused overcompression, increased film hardness, and hindered photocatalyst loading. The optimal parameters for film preparation using recycled HIPS were 140 °C and 90 kg cm⁻². Recycled HIPS containing hydrophilic additives exhibited better photocatalytic performance than virgin HIPS. Under optimal conditions, all three types of recycled plastic were effectively pressed into film. After 15 cycles of simulated solar irradiation, HIPS(<em>R</em>)/PNT exhibited 73.17% acid red 1 decolorization and 92.82% catalyst retention.

Significant research has focused on developing catalytic systems using both precious (<em>e.g.</em>, Pt, Pd and Rh) and non-precious metals, which are highly active due to their efficient H₂ activation and intermediate activation properties. However, the catalytic performance of these metals can vary significantly depending on the nature of the support material. Understanding the behaviour of supported metal, the properties of the support, and their interaction is crucial for optimising reductive amination processes. This review examines the roles of both precious and non-precious metals in intermediate and H₂ activation on the catalyst surface. It also explores how the intrinsic properties of the supports – such as acidic, basic and neutral characteristics – affect catalytic performance. Key factors like the formation of frustrated Lewis pair (FLP), surface acidity, and structural features (<em>e.g.</em>, morphology, exposed facets and particle size) are discussed to comprehensively understand their influence on the catalytic process.

The presence of basic sites in the Au–Cu/HAP catalysts contributes positively to their catalytic activity.

This could be attributed to the activation and oxidation of hydroxyl groups, which are the result of the combined action of basic sites and Au active sites, and the basic sites are sufficient in all catalysts.
