The unique one-dimensional nanoporous structure and the reactive external and internal surfaces make halloysite nanotube (HNT) an interesting nanomaterial for various applications. HNT is a green nanomaterial because it is easily available from abundant deposits in nature and is biocompatible with low cytotoxicity. After a brief introduction on the structure of HNT, recent advances in surface modification of HNT and its functional organic-inorganic nanohybrids including hybrid nanocontainers, flame retardant nanocomposites, dye removal adsorbents, liquid marbles, and superamphiphobic coatings are introduced.

Environmental catalysis plays a crucial role in sustainable development by the design of novel catalytic materials and technologies. Several environmental issues are addressed by catalytic processes such as decomposition of pollutants for air, water and soil remediation, hydrogen production, CO2 reduction and biomass valorization, just to name a few. This contribution aims to provide a general overview of the main concepts and current advances in the environmental catalysis field. Special attention has been paid to photocatalysis and electrocatalysis, as sub‐areas of catalysis with tremendous potential in sustainable applications, in particular with regard to the promotion of sustainable energies. In this contribution, the partnership between Catalysis and Green Chemistry is presented, in a comprehensive way, as an open research line which is imperative and decisive for a more sustainable future.

Nanoparticles, being objects with high surface area are prone to agglomeration. Immobilization onto solid supports is a promising method to increase their stability and it allows for scalable industrial applications, such as metal nanoparticles adsorbed to mesoporous ceramic carriers. Tubular nanoclay - halloysite - can be an efficient solid support, enabling the fast and practical architectural (inside / outside) synthesis of stable metal nanoparticles. The obtained halloysite-nanoparticle composites can be employed as advanced catalysts, ion-conducting membrane modifiers, inorganic pigments, and optical markers for biomedical studies. Here, we discuss the possibilities to synthesize halloysite decorated with metal, metal chalcogenide, and carbon nanoparticles, and to use these materials in various fields, especially in catalysis and petroleum refinery.
