Heavy Metals Contamination: Environmental Threats and Removal Using g-C₃N₄ Nanosheets

  In recent years, the rapid growth of several industries to meet human demands has led to environmental degradation and pollution. One of the biggest problems our world is currently facing is environmental degradation. Water, soil, and air are being dangerously contaminated by industrial processes, agricultural chemicals, plastic trash, and heavy metals. Conventional cleanup techniques are frequently costly, cumbersome, and occasionally ineffective. However, nanotechnology has shown promise as an environmental remediation approach in recent years. Scientists are developing powerful tools to eliminate pollutants more effectively and sustainably by using nanoscale materials. Designing and modifying materials at the nanoscale (1–100 nm) as per the requirements for various applications is known as nanotechnology. When the dimension of a bulk material is reduced to the nanoscale level, the material starts to display several distinctive physical, microstructural, optical, chemical, el...

The majority of the materials in our environment are in bulk form and are made up of one or more elements or their chemical compounds. Materials are typically found in three states in nature: solid, liquid, and gaseous. Depending on how the atoms or molecules are arranged, the materials that exist in solid form can be roughly divided into two groups: crystalline and non-crystalline solids. Atoms or molecules are arranged in regular, periodic patterns in crystalline structures. The majority of solids are typically crystalline. The reason for this is that when ordered structures are formed, more energy is released than when disordered structures are formed. Because low-energy states are more stable according to natural principles, solids tend to adopt crystalline structures, which are low-energy states. Single crystals and polycrystalline solids are the two main categories into which crystalline solids are further divided. In contrast to a polycrystalline solid, which is made up of an ...
