A holistic approach to the separation, storage, and transportation of crude hydrogen
No full textIn this Nature Energy article, Ding Ma, Yifeng Zhu, and colleagues design a Cu/Al2O3 inverse catalysts for the interconversion between γ-butyrolactone and 1,4-butanediol. The precisely controlled catalyst structure and catalytic conditions result in a notable efficiency of the catalytic cycle and ultimately offer a promising strategy toward green hydrogen economy
Updates on the Roadmap for Photocatalysis
No full textIntroduction:
“Here comes the sun, and I say it’s alright”. The line from the famous and comforting Beatles’ song sounds like a perfect slogan for today’s crusade toward a more sustainable world. A never-tiring memento that, as long as the Sun shines in the sky, there will always be hope to heal a world suffering from an impressive increase in energetic demand. Sunlight brings a gigantic energy pack, and modern scientists are investing a huge amount of time, resources, and intellectual exercise into best exploiting it. Therefore, the fast-growing number of discoveries on photocatalysis comes as no surprise, and quite obviously they are accompanied by a ballistic number of publications (Figure 1). However, is this latter number truly justified or is the chain of events pining for sustainability and clean energy generating an overpopulation of contributions to the topic? Assuming that all such publications always reach a minimum standard of quality and novelty, the question for now must remain unanswered, because research is an unpredictable animal that can feed from any little fruit. However, a different but relevant question could be possibly answered: is it possible to establish a common protocol, set of rules, that makes all these publications useful for moving forward in a harmonized fashion the knowledge on photocatalysis
Catalysis by Ceria and Related Materials, 2nd Edition: Volume 12
No full textThis book follows the 2002 edition of Catalysis by Ceria and Related Materials, which was the first book entirely devoted to ceria and its catalytic properties. In the ten years since the first edition a massive amount of work has been carried out in the field, and ceria has gained a prominent position in catalysis as one of the most valuable material for several applications. This second edition covers fundamental and applied aspects of the latest advances in ceria-based materials with a special focus on structural, redox and catalytic features. Special emphasis is given to nano-engineered and nano-shaped systems which are a key factor in the predictive and rational design of ceria with novel properties. In addition, the book presents recent advances in emerging and traditional large-scale applications of ceria in catalysis, such as the treatment of emissions from mobile sources (including diesel and gasoline engines). The primary readership includes catalysis and material science researchers from academy and industry and postdoctorate and graduate students in chemistry, chemical engineering and physics
What Is to Be Expected from Heterogeneous Catalysis in the Pipeline to Circular Economy?
No full textModern society requires a change in the philosophy of doing science, which faces the enormous challenge of being compatible with the new sustainability principles. Inorganic chemistry holds the keys to accelerate the transition given that most chemical processes or technology devices rely on the use or integration of inorganic materials. In particular, heterogeneous catalysis has a central role in promoting the transition from a linear economy to a circular one. To accomplish this, it is imperative that the modern schemes for catalysis will adopt a holistic approach based on sensible choice of raw materials, reliance on clean energy inputs and establishment of a robust framework of resource use and recovery. Some of these concepts are analysed here and discussed in Ref. [to a few selected examples

Photocatalysis for Hydrogen Production and CO2 Reduction: The Case of Copper-Catalysts
No full textProblems derived from climate change dictate the reestablishment of our prospective in energy production. In this direction, converting solar energy through photocatalysis into suitable fuels such as hydrogen and carbon‐based fuels by water splitting and CO2 reduction, respectively, has been established as a promising approach. Currently, the main concern in this field is the development of cost‐effective and efficient photocatalysts. Among the different systems studied, Cu‐based photocatalysts are considered attractive candidates for both applications due to their relative low‐cost, the natural abundance of the constituents and their promising reactivity. In this review, the current progress in the field of Cu‐based photoactive materials for both H2 production and CO2 reduction will be discussed. Finally, an outlook on the challenges and future research directions is given
