ABSTRACT
Ceramic is an ancient material and serves as natural air conditioner, filter for toxic gases, and industrial waste water; major concern of global warming. Growing population exponentially using vehicles, civil construction, and industries, and disposes tons of heat, toxic gases, and chemical compounds either in air or water. In preference, metal catalyst along with ceramic substrate facilitate gas filtration, however, chemical engineers and material researchers are effectively solving water pollution by abundant solar energy and waste mechanical energy. Several critical issues including smart glass, water purification, and minimization of water usability by nanostructured ceramics are focused in the perspective of environment research.
