Sommario/riassunto

Heterogeneous catalysis, exploiting photo- and electrochemical reactions, has expanded rapidly in recent decades, having undergone various developments, especially from both energetic and environmental points of view. Photocatalysis plays a pivotal role in such applications as water splitting and air/water remediation. Electrocatalysis can be found in a large array of research fields, including the development of electroanalytical sensors, wastewater treatment, and energy conversion devices (e.g., batteries, fuel and solar cells, etc.). Therefore, the fine control of the synthetic procedures, together with extensive physicochemical characterisations of the tailor-made catalytic nanomaterials, are of fundamental importance to achieving the desired results. The present book will include recent enhancements in oxide/metal nanoparticles for photocatalytic and electrocatalytic applications, especially in the fields of pollutants abatement and energy conversion.

Sommario/riassunto

Essential oils (EOs) and microbial/plant-based volatile organic compounds (VOCs) are being used in an increasing number of sectors such as health, cosmetics, the food industry and, more recently, agronomy. In agronomy, they are employed as bio-herbicides and bio-pesticides due to their their insecticidal, antifungal, and bactericidal effects. Several EO-based bio-pesticides are already registered. Essential oils and other VOCs are 100% bio-based and present numerous additional advantages. They contain a great number of structurally diverse compounds that frequently act in synergy; they are thus less subject to resistance. As highly volatile compounds are found in EOs and VOCs, they typically cause no residue problems in food products or in soils. Indeed, the supply of EOs can be really challenging because they are frequently produced in restricted areas of the world with prices and chemical composition fluctuations. Besides, while the high volatility of EOs and VOCs is interesting for some specific applications, it can be a problem when developing a bio-pesticide with long lasting effects. Finally, EOs are frequently phytotoxic, which is perfect for herbicide formulations, but not for other applications. In both cases, the development of a proper formulation is essential. Owing to the current attraction for natural products, a better understanding of their modes of biological action is of importance for



the development of new and optimal applications.
