Innovative Materials for Energy Conversion and Storage

Topic Information

Dear Colleagues,

To meet the sustainable development goals, great efforts have been devoted to developing clean energy conversion and storage systems across the globe. Material innovation is a vital part of achieving high-efficiency energy conversion and storage. Today, many effective optimization methods have been applied to material innovation, and some important progress has been made in the research for energy conversion and storage materials. However, there are still many common challenges to realizing high-efficiency energy conversion and storage, including materials’ structure design, the REDOX mechanism in energy conversion and storage, the behavior of charge transport, and so on. Thus, this topic invites innovative articles on diverse aspects of energy conversion and storage materials, which include but are not limited to:

• Innovative Materials for Lithium/Sodium Ion Batteries;
• Innovative Materials for Metal-Air Batteries;
• Innovative Materials for Supercapacitors;
• Innovative Materials for Fuel Cells;
• Innovative Materials for Water Splitting;
• Innovative Materials for CO₂ Reduction Reaction;
• Innovative Materials for Nitrogen Reduction Reaction;
• Innovative Materials for Biology Energy.

All types of manuscripts (original research, reviews, short communications) are welcome.

Abstract

The controlled growth of Cu₂S nanoarrays was constructed by a facile two-step impregnation synthesis route. The as-synthesized Cu₂S/CuO@Cu samples were precisely characterized in terms of surface morphology, phase, composition, and oxidation states. At the laser irradiation of 808 nm, [...] Read more.

The controlled growth of Cu₂S nanoarrays was constructed by a facile two-step impregnation synthesis route. The as-synthesized Cu₂S/CuO@Cu samples were precisely characterized in terms of surface morphology, phase, composition, and oxidation states. At the laser irradiation of 808 nm, Cu₂S/CuO@Cu heated up to 106 °C from room temperature in 120 s, resulting in an excellent photothermal conversion performance. The Cu₂S/CuO@Cu exhibited excellent cycling performance—sustaining the photothermal performance during five heating-cooling cycles. The finite difference time domain (FDTD) simulation of optical absorption and electric field distributions assured the accuracy and reliability of the developed experimental conditions for acquiring the best photothermal performance of Cu₂S/CuO@Cu.

GYAGG:Tb (Ce) scintillators have been confirmed to be promising sources of light emission when excited by an intense 150 keV electron beam. The saturation of the scintillation yield under such excitation conditions has been studied. To explain the results obtained, a model that considers the Auger quenching mechanism was used. The Ce-doped material did not show saturation, whereas a moderate 30% drop of the yield was measured in the Tb-doped sample at the highest excitation beam intensity ~1 A/cm². This put forward a way to exploit the Tb-doped scintillator for indirect β-voltaic batteries. Full article

Abstract

It is of great importance to promote charge separation in photocatalysts for enhanced photocatalytic activity under visible light irradiation. In this work, a type-II heterostructured photocatalyst was constructed by compositing phosphorus-doped g-C₃N₄ (P-CN) and Rh-doped SrTiO₃ (Rh-STO) via a [...] Read more.

It is of great importance to promote charge separation in photocatalysts for enhanced photocatalytic activity under visible light irradiation. In this work, a type-II heterostructured photocatalyst was constructed by compositing phosphorus-doped g-C₃N₄ (P-CN) and Rh-doped SrTiO₃ (Rh-STO) via a thermal calcination treatment. A series of characterizations were conducted to investigate the structure of heterostructured P-CN/Rh-STO. It was found that Rh-STO interacted with in situ generated P atoms from the decomposition of P-CN during the calcination process, thus leading to the formation of heterojunction of P-CN/Rh-STO. Compared with the single component, i.e., P-CN or Rh-STO, the obtained P-CN/Rh-STO showed superior photocatalytic activity to that of both P-CN and Rh-STO due to the effective charge separation across the heterojunction between P-CN and Rh-STO.
