“…There is a distinct variation observed in the electronic structure of the samples when the distortion of the VO 4 3-tetrahedron occurs. This distortion is due to the lone pair electron of Bi 3+ in the local structure of the BiVO 4 .There is a change in the extent of overlapping of Bi6s and O2p with the distortion of VO 4 3-tetrahedron. This overlapping is directly proportional to the degree of distortion which in turn helps in the mobility of photogenerated holes [18].…”

“…The differences in the intensities and peak position of the bands in the Raman spectra clearly demonstrate the variations in the local crystal structure among the powder samples, as the frequencies related to the VO 4 tetrahedron and V-O bonds are directly related to the interactive forces between Bi +3 and V 5+ cations. It can be noticed from the relative intensities of the Raman spectra among the powder samples that VO 4 3-tetrahedron with different VO 4 space symmetries were formed. It can also be noticed that variations in one of the V-O bond length among the powder samples can be explained on the basis of packing of the structure.…”

“…The band structure in scheelite-monoclinic BiVO 4 is formed by the Bi 6s, O2p and V3d orbitals; among them, valence band is formed by the hybrid of Bi6s and O2p and conduction band by V3d [25]. There is a distinct variation observed in the electronic structure of the samples when the distortion of the VO 4 3-tetrahedron occurs. This distortion is due to the lone pair electron of Bi 3+ in the local structure of the BiVO 4 .There is a change in the extent of overlapping of Bi6s and O2p with the distortion of VO 4 3-tetrahedron.…”

“…Solar energy being the most abundant energy source has been widely exploited for thermal and electrical power generation [1], [4]; however, due to a higher convenience of a means of chemical energy storage, such as H 2 , as compared to electricity, solar fuels have been regarded as one of the most promising technological concepts due to its potential higher efficiency and environmental suitability [5]- [7].…”

“…Secondary and trace nutrients are doubtlessly beneficial for plant growth, but they are not indispensable for human life [12]. Provided humanity learns how to harvest effectively the energy available from renewable resources [13], long-term supply of reactive nitrogen from the atmosphere and of potassium from seawater should be assured. Other mineral and metal resources are replaceable by similar elements performing the same functionality.…”

Abstract:In the aftermath of the adoption of the Sustainable Development Goals (SDGs) and the Paris Agreement (COP21) by virtually all United Nations, producing more with less is imperative. In this context, phosphorus processing, despite its high efficiency compared to other steps in the value chain, needs to be revisited by science and industry. During processing, phosphorus is lost to phosphogypsum, disposed of in stacks globally piling up to 3-4 billion tons and growing by about 200 million tons per year, or directly discharged to the sea. Eutrophication, acidification, and long-term pollution are the environmental impacts of both practices. Economic and regulatory framework conditions determine whether the industry continues wasting phosphorus, pursues efficiency improvements or stops operations altogether. While reviewing current industrial practice and potentials for increasing processing efficiency with lower impact, the article addresses potentially conflicting goals of low energy and material use as well as Life Cycle Assessment (LCA) as a tool for evaluating the relative impacts of improvement strategies. Finally, options by which corporations could pro-actively and credibly demonstrate phosphorus stewardship as well as options by which policy makers could enforce improvement without impairing business locations are discussed.

Renewable electricity such as wind and solar power provides a meaningful sustainable energy source for remote regions, but its intermittency in nature and inherently low power intensities and energy densities require suitable energy storage mechanisms to make it viable. Alkaline water electrolysis can serve as such a means of energy storage. This article outlines a distributed energy system concept involving water electrolysis. The promises of the distributed energy system are discussed in terms of the development and research of water electrolysis. The technical studies for water electrolysis were evaluated and assessed with current literature. By analyzing the opportunities and limitations of water electrolysis in matching their power scales with feasible renewable electricity sources, this work showed that a distributed energy system with a capacity of 200 kW is technically and economically feasible using currently available technologies, indicating the potential of this distributed system for energy supply for remote communities. This work also identifies several key areas where further R&D effort is needed in order to help deploy water electrolysis and hydrogen fuel cell technologies in the utilization of renewable energy.
