1) Intelligent air conditioning building materials
Mimicking the characteristics of warming in winter but cooling in summer for cave dwellings, the intelligent building materials were synthesized hydrothermally and this material also could provide smart properties of energy saving, comfortable and safe living for buildings.
2) Biocompatible purification materials for sewage treatment
Inspired by the integrated adsorption/degradation purification performances of porous paddy soil, the paddy-soil-like superior purification material was hydrothermally synthesized for sewage treatment, which could give play to both inorganic adsorption and organic decomposition, and also reduce the sludge production to the maximum extent.
3) Treatment of nuclear wastes
Considering the geological evolution of pollucite to soil, the Cs-polluted soil (or incineration ash) has been hydrothermally converted into pollucite for immobilization of the radioactive Cs. This technique can provide a safe disposal method for radioactive Cs especially for the case of Fukushima in Japan.
4) Hydrothermal solidification of inorganic wastes to building materials
Simulating the diagenetic process of sedimentary rocks underground, the solid wastes such as fly ash, municipal incinerator refuse ash, slag, waste ceramics/glass, sewage sludge and alluvial sediment could be hydrothermally solidified into functional building materials and revetment materials.
5) Hydrothermal remediation of contaminated urban brownfield into soils
Based on the geological evolution of soil, the polluted soil (brownfield) was hydrothermally reconstructed and converted into environmental minerals, e.g. zeolites, which have the capability of immobilizing the contaminated heavy metals in-situ within its structure. This study might provide a quick method for soil remediation, especially for the remediation of urban brownfield.
6) Recycling of CO2
CO2 is recognized as a new type of carbon source because of non-toxic, extensive sources and low cost. CO2 could be converted into valuable carbonaceous substances and various chemicals, e.g. graphite and graphene at low temperature.
