Photoactive nanoarchitectures based on clays incorporating TiO2 and ZnO nanoparticles.

摘要: Thought as raw materials clay minerals are often disregarded in the development of advanced materials. However, clays natural and synthetic origin constitute excellent platforms for developing nanostructured functional numerous applications. They can be easily assembled to diverse types nanoparticles provided with magnetic, electronic, photoactive or bioactive properties, allowing overcome drawbacks other substrates design nanoarchitectures. Within this scope, special relevance production they offer an advantageous way stabilization immobilization metal-oxide nanoparticles. The controlled assembly under mild conditions titanium dioxide zinc oxide give clay–semiconductor nanoarchitectures summarized critically discussed review article. possibility use starting components showing different morphologies, such layered, fibrous, tubular immobilize these mainly plays a role i) control their size distribution on solid surface, ii) mitigation suppression nanoparticle aggregation, iii) hierarchical selectivity enhancements catalytic transformation improved overall reaction efficiency. This article tries also present new steps towards more sophisticated but efficient highly selective incorporating photosensitizer elements tuning semiconductor–clay photoactivity.
