The major energy utilization methods of fossil and biomass fuels include combustion, gasification, liquefaction, and so on. However, anthropogenic impacts on the environment has aroused much attention in recent years. CO2 emitted during the utilization process is one of the main contributors to the global warming. Besides, some pollutions (e.g. heavy metal elements) contained in the flue gas also bring big risks for the environment. Therefore, renewable and sustainable materials and energy utilization technologies should be further developed to address the environmental problems under the premise of favorable conversion efficiency.

This Special Issue "New Trends in Sustainable Materials for Energy Conversion, CO2 Capture and Pollution Control" mainly covers research in fundamental and applied sciences of renewable and sustainable materials during the energy utilization and pollution control processes. The scope of interests includes but is not limited to the following topics:

1. Thermochemical conversion of fossil and biomass fuels

2. Pollution control

3. CO2 capture

4. Process simulation

5. Renewable and sustainable materials

Renewable and sustainable, Energy conservation, Pollution reduction, CO2 capture, Simulation

  • Effects of Porous Graphene on LiOH Based Composite Materials for Low Temperature Thermochemical Heat Storage
  • Abstract Thermochemical heat storage material inorganic hydrate LiOH is selected as a promising candidate material for storing low-temperature heat energy because of its high energy density (1440 kJ/kg) and mild reaction process. However, the low hydration rate of LiOH limits the performance of low temperature thermochemical heat storage system as well as the thermal conductivity. In this study, porous-graphene/LiOH composite thermochemical heat storage materials with strong water sorption property and higher thermal conductivity were synthesized by hydrothermal process. The experimental results show that the hydration rate of the composites was greatly improved. The heat storage density of the composite materials was… More

  • Hydrogenated Amorphous Carbon Films from Palmyra Sugar
  • Abstract A simple, highly reproducible, and environmentally friendly method is a considered approach in generating renewable energy materials. Here, hydrogenated amorphous carbon (a-C) films have been successfully prepared from palmyra liquid sugar, employing spin-coating and spraying methods. Compared with the former method, the latter shows a significance in producing a better homogeneity in particle size and film thickness. The obtained films have a thickness of approximately 1000 to 100 nm and contain an sp2 hexagonal structure (~70%) and sp3 tetrahedral configuration (~30%) of carbons. The introduction of boron (B) and nitrogen (N) as dopants has created the local structural modification of… More

  • Microparticle Effect of Carbon Dioxide Hydrate Crystal Nucleus in Reaction Kettle
  • Abstract This study analyzed the partial effect of carbon dioxide hydrate in reaction kettle experiments. The particle and bubble characteristics of the crystal nucleus during carbon dioxide hydrate decomposition were observed under the microscope. The results showed that in the temperature range of 0.5°C–3.5°C, the pressure range of 3 MPa– 5.5 MPa, phase characteristics in the reaction kettle changed in a complex fashion during carbon dioxide hydrate formation. During hydrate decomposition, numerous carbon dioxide bubbles were produced, mainly by precipitation at high temperatures or in the hydrate cage structure. The hydrate crystal nucleus initially exhibited fluidity in the reaction. However, as… More
