Special Issue Information

Dear Colleagues,

The environment and its resources are the basis of human survival and development. Under the current concept of sustainable development, research on mineral resources, hydrogeology, and environmental sustainability has a profound impact on energy exploitation, social development, and people's lives. The traditional exploitation of mineral resources blindly consumes and wastes the limited geological resources, destroys the ecological environment in which human beings live, and ruins the natural ecological balance. Scientists must deeply understand the actual connotations of sustainable development, and under the new requirements of this concept, they must actively adjust their working ideas, change their working methods, take a long-term view, correctly understand the existing problems in the current stage of mine hydrogeological exploration and environmental geology work, and actively seek long-term and stable countermeasures.

Recently, the application of microorganisms in mineral resource exploitation and environmental protection has received more and more attention. Microbial mining technology and the environmental remediation concept, with their many advantages, such as a simple process, less investment, and less environmental pollution, are playing a significant role in this field, showing great potential to have a profound impact on human beings. However, microbial mining is not well understood for a variety of reasons, hence the need for further research into this technology.

Therefore, this Special Issue will introduce the new ideas and experimental results of the application of microbial technology in the research field of mineral resources, hydrogeology, and environmental sustainability, and explore the performance and integration of different bioremediation technologies to achieve a sustainable use of the environment and its resources.

The global serious pollution situation urgently needs green, efficient, and sustainable development methods to achieve heavy metal pollution control. The photocatalytic properties of anatase are sufficient to achieve pollution control by providing photoelectrons to harmful heavy metals. However, since natural anatase particles tend to agglomerate and deactivate in water, most studies have been conducted to prepare TiO2–biochar nanocomposites using chemical synthesis methods. In the present study, we utilized pyrolytic sintering to load natural anatase onto biochar to obtain natural anatase–biochar (TBC) composites. Characterization tests, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS), showed that anatase was uniformly partitioned into the surface and pores of biochar without destroying the lattice structure. Due to its photocatalytic properties, TBC degraded Cr (VI) by 99.63% under light conditions. This is 1.58 times higher than the dark condition. Zeta potential showed that the surface of the TBC was positively charged under acidic conditions. The charge attraction between TBC and chromium salt was involved in the efficient degradation of Cr (VI). Different sacrificial agents as well as gas purge experiments demonstrated that photoelectrons (e) and superoxide radicals (O2) dominated the degradation of Cr (VI). TBC has the characteristics of high efficiency, stability, and sustainability. This may provide a new idea for the preparation of photocatalytic materials and the realization of environmental protection and sustainable development through heavy metal pollution control.
