Currently, nanomaterials are considered to be the backbone of modern civilization. Especially in the energy sector, nanomaterials (mainly, carbon- and metal oxide/hydroxide-based nanomaterials) have contributed significantly. Among the various green approaches for the synthesis of these nanomaterials, the microwave-assisted approach has attracted significant research interest worldwide. In this context, it is noteworthy to mention that because of their enhanced surface area, high conducting nature, and excellent electrical and electrochemical properties, carbon nanomaterials are being extensively utilized as efficient electrode materials for both supercapacitors and secondary batteries. In this review article, we briefly demonstrate the characteristics of microwave-synthesized nanomaterials for next-generation energy storage devices. Starting with the basics of microwave heating, herein, we illustrate the past and present status of microwave chemistry for energy-related applications, and finally present a brief outlook and concluding remarks. We hope that this review article will positively convey new insights for the microwave synthesis of nanomaterials for energy storage applications.

Renewable energy in Central Asia: An overview of potentials, deployment, outlook, and barriers

AEMFC is becoming a prominent technology in portable energy sources. In an attempt to make it economical, non-platinum catalysts are necessary to recruit in the application. Numerous researches are accomplished on the development of platinum-free catalysts. This review summarizes the advancements in the synthesis of catalysts consisting of different components and structures. Rotating ring-disk electrode (RRDE) and fuel cell tests are commonly employed to evaluate the activity for oxygen reduction reaction (ORR) and performances of the catalysts. Here, along with the synthesis and characterization data, this information is assembled and analyzed correlating different factors. To the best of our knowledge, 13 among 203 catalysts have overcome the peak power density (PPD) threshold of 1000 mW.cm-2, which belong to the four categories i.e. Metal-Nitrogen-Carbon (M-N-C), Bimetals-Nitrogen-Carbon (MM-N-C), Transition metal oxides (TMO), and non-metallic catalysts (NMC). The improvement in catalyst’s porosity, surface area, conjugation of active sites, and thereby the synthesis procedures have a great effect on the ORR activity and fuel cell performance. In addition to catalyst properties, there are several other significant factors involved such as water management, properties of anion-exchange membrane (AEM) and anion-exchange ionomer (AEI), optimized operating conditions, etc. The previously low-performing catalysts with high ORR activity cannot be ignored from the top-tier catalysts, since enormous improvements are accomplished in membrane conductivity and water management recently.

Review on equipment configuration and operation process optimization of hydrogen refueling station

Renewable energy has become an important choice to solve the energy crisis and environmental problems. A sustainable development needs policies and strategies policies, which can improve energy efficiency and reduce greenhouse gas emissions. By collecting the research results released by relevant statistical departments and authoritative institutions, this paper summarizes the international energy development situation, systematically combs the energy development situation of the European Union, United States, Australia, India, Brazil. The development trend of wind, solar, biomass, geothermal, ocean, and hydrogen energy have been analyzed. In addition, this paper proposes that China should draw up its own development path of renewable energy from international development experience, and actively explore renewable energy policies and strategies adapted to different stages of development.
