This research explores the transformative potential of nanomaterial developments in tending to water and soil contamination through economical natural remediation procedures. Three unmistakable nanomaterials, Nanoparticle A, Nanocomposite B, and Nanotube C, were synthesized and efficiently assessed for their adequacy in poison expulsion. In adsorption tests, Nanocomposite B showed remarkable lead expulsion capacity, outperforming Nanoparticle A and Nanotube C with values of 30 mg/g. Catalytic debasement tests illustrated Nanocomposite B’s predominant proficiency in corrupting phenol, accomplishing a noteworthy 68%, outflanking Nanotube C and Nanoparticle A. A comprehensive natural compatibility appraisal uncovered decreased ecotoxicity and cytotoxicity files for Nanocomposite B, situating it as a naturally inviting choice for remediation. Comparative investigations with related works exhibit the importance of fitting nanomaterial properties focused on poison expulsion. The promising results emphasize Nanocomposite B’s potential as a maintainable and multifunctional arrangement for water and soil remediation. This investigation contributes profitable insights to the developing field of nanotechnology-enabled natural administration, emphasizing the requirement for the capable sending of nanomaterials to attain long-term environmental and human well-being benefits.

“…In recent years, the development of single-atom catalyst (SAC) technology has provided new ideas for the development of high-performance photocatalysts. − Also, SACs have near-100% atomic utilization, selectivity, stability, and well-defined coordination structure, which can be used for the rational design and development of more efficient photocatalysts with low cost. − However, it is vital to find supporting materials that can stabilize the single metal atom and construct a synergistic site to assist the single-atom site. More importantly, the supporting materials must be able to form a stable composite structure with the photocatalysts.…”

Single-atom catalyst technology with near-100% atomic utilization and a well-defined coordination structure has provided new ideas for designing high-performance photocatalysts, which is also beneficial for reducing the usage of noble metal cocatalysts. Herein, a series of single-atomic MoS 2 -based cocatalysts where monoatomic Ru, Co, or Ni modify MoS 2 (SA-MoS 2 ) for enhancing the photocatalytic hydrogen production performance of g-C 3 N 4 nanosheets (NSs) are rationally designed and synthesized. The 2D SA-MoS 2 /g-C 3 N 4 photocatalysts with Ru, Co, or Ni single atoms show similar enhanced photocatalytic activity, and the optimized Ru 1 −MoS 2 /g-C 3 N 4 photocatalyst has the highest hydrogen production rate of 11115 μmol/h/g, which is about 37 and 5 times higher than that of pure g-C 3 N 4 and MoS 2 /g-C 3 N 4 photocatalysts, respectively. Experimental and density functional theory calculation results reveal that the enhanced photocatalytic performance is mainly attributed to the synergistic effect and intimate interface between SA-MoS 2 with well-defined coordination single-atomic structures and g-C 3 N 4 NSs, which is conducive to the rapid interfacial charge transport, and the unique single-atomic structure of SA-MoS 2 with modified electronic structure and appropriate hydrogen adsorption performance offers abundant reactive sites for enhancing the photocatalytic hydrogen production performance. This work provides new insight into improving the cocatalytic hydrogen production performance of MoS 2 by a single-atomic strategy.
