The energy consumption from the expanding use of information and communications technology (ICT) is unsustainable with present drivers, and it will impact heavily on the future climate change. However, ICT devices have the potential to contribute significantly to the reduction of CO 2 emission and enhance resource efficiency in other sectors, e.g., transportation (through intelligent transportation and advanced driver assistance systems and self-driving vehicles), heating (through smart building control), and manufacturing (through digital automation based on smart autonomous sensors). To address the energy sustainability of ICT and capture the full potential of ICT in resource efficiency, a multidisciplinary ICT-energy community needs to be brought together covering devices, microarchitectures, ultra large-scale integration (ULSI), high-performance computing (HPC), energy harvesting, energy storage, system design, embedded systems, efficient electronics, static analysis, and computation. In this chapter, we introduce challenges and opportunities in this emerging field and a common framework to strive towards energy-sustainable ICT.

“…[20][21][22] Many studies have reported that electrode nanomaterials with specific morphologies exhibit excellent electrochemical performance in LIBs. [23][24][25][26][27][28][29][30][31] Herein, we synthesized Cu 2 O nanostructure anodes with different morphologies by adopting a reducing agent with and without polyvinylpyrrolidone (PVP) as a surfactant. The electrochemical performances of cubic and octahedral Cu 2 O with {100} and {111} facets, respectively, were studied as anode materials for LIBs.…”

An octahedron-shaped Cu 2 O nanostructure electrode having the {111} facets with high surface energy favourable for lithium ion transport revealed an enhanced conversion reaction mechanism with high reversible capacity and high rate cycling performance.Well-defined nanostructure electrodes are known to have improved lithium ion reaction properties for lithium-ion batteries. Herein, we prepared shape-controlled Cu2O nanostructures as an anode material using ascorbic acid as a reducing agent with and without polyvinylpyrrolidone (PVP) as a surfactant. Using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction method, we observed that the sample prepared in the absence of PVP exhibited cubes with dominant {100} facets, whereas octahedral Cu2O nanostructure with dominant {111} facets was formed in the presence of PVP. During the charge-discharge process, an octahedron-shaped Cu2O nanostructure electrode having the {111} facets favourable for lithium ion transport revealed an enhanced conversion reaction mechanism with high reversible capacity and high rate cycling performance, due to low charge transfer resistance and high lithium ion diffusion coefficient.

“…Cuprous oxide (Cu 2 O) is a well-known p-type semiconductor and has a direct small bandgap of 2.2 eV, which endows it promising applications in solar energy conversion [12], as an electrode for lithium-ion batteries [13], gas sensors [14], and photocatalytic degradation of organic pollutants and decomposition of water into O 2 and H 2 under visible light [15-17]. So far, great efforts have been devoted to the synthesis of cuprous oxide with different shapes and sizes.…”

Facile synthesis of hollow Cu2O octahedral and spherical nanocrystals and their morphology-dependent photocatalytic properties

Herein, we report that octahedral and spherical Cu 2 O samples with hollow structures are synthesized in high yield by reducing Cu(EDA) 2 2+ complex with hydrazine. A series of experiments are carried out to investigate the factors which impact on the morphology of the Cu 2 O samples. It is observed that ethylenediamine (EDA) serves as a molecular template in the formation of hollow structure. Octahedral Cu 2 O with solid structure is prepared without EDA. When EDA is added, Cu 2 O sample with hollow structure is formed. Different morphologies of Cu 2 O such as spherical and octahedral could be obtained by adjusting the concentration of EDA and NaOH. The temporal crystal growth mechanism is proposed. Furthermore, the photocatalytic activities of the as-prepared Cu 2 O nanoparticles are evaluated by monitoring two dyes (methyl orange and congo red) using UV-visible spectrophotometer. Results show that the order of photocatalytic activity of Cu 2 O with different morphologies is as follows: hollow octahedral morphology > hollow sphere morphology > solid octahedral morphology. The hollow octahedral Cu 2 O nanoparticles would be a promising material on applications for photocatalytic degradation of organic pollutants.
