"Colloidal quantum materials are nanocrystals containing hundreds to thousands of atoms that exhibit unique properties resulting from their small finite dimensions. The extraordinary flexibility in tuning their properties via composition, size- and dimensionality-related quantum confinement effects and surface engineering combined with their scalable bottom-up manufacturing has already led to their commercialization in different light-emitting applications, such as materials for displays and as fluorescent agents for imaging and sensing. Beyond light emission, harnessing absorbed light energy to perform useful chemical work is an important new avenue for diverse applications of the colloidal quantum materials. Here, we introduce the colloidal quantum materials and their virtues, focusing on the “all-in-one system” concept for semiconductor–metal hybrid nanoparticles acting as photocatalysts. Next, their emerging photocatalytic functionalities are highlighted, including their action as photocatalysts for solar-to-fuel conversion and as photoinitiators for photo-curing and biomedical applications, such as phototherapy, sterilization, and diagnostics."

Hybrid nanoparticles combine two or more disparate materials on the same nanosystem and represent a powerful approach for achieving advanced materials with multiple functionalities stemming from the unusual materials combinations. This review focuses on recent advances in the area of semiconductor–metal hybrid nanoparticles. Synthesis approaches offering high degree of control over the number of components, their compositions, shapes, and interfacial characteristics are discussed, including examples of advanced architectures. Progress in hybrid nanoscale inorganic cage structures prepared by a selective edge growth mechanism of the metal onto the semiconductor nanocrystal is also presented. The combined and often synergistic properties of the hybrid nanoparticles are described with emphasis on optical properties, electronic structure, electrical characteristics, and light induced charge separation effects. Progress toward the application of hybrid nanoparticles in photocatalysis is overviewed. We conclude with a summary and point out some challenges for further development and understanding of semiconductor–metal hybrid nanoparticles. This progress shows promise for application of hybrid nanoparticles in photocatalysis, catalysis, optical components, and electronic devices.
