Noble Metal Free Catalysts for Hydrogen Generation from Aqueous Solutions


Book Description

The current energy crisis is becoming more and more serious due to the industrial development and increasing population. Mimicking photosynthesis in plants provides a new way to solve this crisis. The goal is to harness solar energy and convert it into energy stored in chemical bonds such as methanol or hydrogen gas. Currently, most catalysts for proton reduction contain precious metals, such as palladium, platinum, and ruthenium. The main goal of our research is to develop catalysts made of earth abundant materials. By incorporating organic ligands in our complexes, we can make catalysts that have similar catalytic activity as those made of rare metals. Herein I report an iron and a nickel catalysts [sic] that can generate hydrogen from water.

Noble Metal-free Electrocatalysts


Book Description

"Electrocatalysts: From Fundamentals to Recent Advances. In the quest for sustainable hydrogen production, the challenge remains to identify new electrocatalysts for water electrolysis. While noble metals are the most effective catalysts for water splitting-a promising pathway to sustainable hydrogen production-they are expensive and scarce. Hence, there is a need to find environmentally friendly, earth abundant, highly stable, and economically viable alternatives. This book provides current state-of-the-art knowledge of a wide range of noble metal-free electrocatalysts for energy applications. Volume 1 reviews materials synthesis and fundamentals of electrocatalysts; noble metal-free electrocatalysts and their roles in metal-air batteries; bio- and graphene-based electrocatalysts; and electrocatalysts based on metal oxides, phosphides, and covalent organic frameworks."--

Materials for Hydrogen Production, Conversion, and Storage


Book Description

MATERIALS FOR HYDROGEN PRODUCTION, CONVERSION, AND STORAGE Edited by one of the most well-respected and prolific engineers in the world and his team, this book provides a comprehensive overview of hydrogen production, conversion, and storage, offering the scientific literature a comprehensive coverage of this important fuel. Continually growing environmental concerns are driving every, or almost every, country on the planet towards cleaner and greener energy production. This ultimately leaves no option other than using hydrogen as a fuel that has almost no adverse environmental impact. But hydrogen poses several hazards in terms of human safety as its mixture of air is prone to potential detonations and fires. In addition, the permeability of cryogenic storage can induce frostbite as it leaks through metal pipes. In short, there are many challenges at every step to strive for emission-free fuel. In addition to these challenges, there are many emerging technologies in this area. For example, as the density of hydrogen is very low, efficient methods are being developed and engineered to store it in small volumes. This groundbreaking new volume describes the production of hydrogen from various sources along with the protagonist materials involved. Further, the extensive and novel materials involved in conversion technologies are discussed. Also covered here are the details of the storage materials of hydrogen for both physical and chemical systems. Both renewal and non-renewal sources are examined as feedstocks for the production of hydrogen. The non-renewal feedstocks, mainly petroleum, are the major contributor to date but there is a future perspective in a renewal source comprising mainly of water splitting via electrolysis, radiolysis, thermolysis, photocatalytic water splitting, and biohydrogen routes. Whether for the student, veteran engineer, new hire, or other industry professionals, this is a must-have for any library.

Photocatalytic Hydrogen Evolution


Book Description

Energy crises and global warming pose serious challenges to researchers in their attempt to develop a sustainable society for the future. Solar energy conversion is a remarkable, clean, and sustainable way to nullify the effects of fossil fuels. The findings of photocatalytic hydrogen production (PCHP) by Fujishima and Honda propose that “water will be the coal for the future”. Hydrogen is a carbon-free clean fuel with a high specific energy of combustion. Titanium oxide (TiO2), graphitic-carbon nitride (g-C3N4) and cadmium sulfide (CdS) are three pillars of water splitting photocatalysts owing to their superior electronic and optical properties. Tremendous research efforts have been made in recent years to fabricate visible or solar-light, active photocatalysts. The significant features of various oxide, sulfide, and carbon based photocatalysts for cost-effective hydrogen production are presented in this Special Issue. The insights of sacrificial agents on the hydrogen production efficiency of catalysts are also presented in this issue.
