  2. Green chemistry - Wikipedia

    en.wikipedia.org/wiki/Green_chemistry

    Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]

  3. Green nanotechnology - Wikipedia

    en.wikipedia.org/wiki/Green_nanotechnology

    The word GREEN in the name Green Nanotechnology has dual meaning. On one hand it describes the environment friendly technologies utilized to synthesize particles in nano scale; on the other hand it refers to the nanoparticles synthesis mediated by extracts of chlorophyllus plants. [ 1 ]

  4. Green photocatalyst - Wikipedia

    en.wikipedia.org/wiki/Green_photocatalyst

    A green source for photocatalyst synthesis refers to a material that is renewable, biodegradable, and has minimal environmental impact during its extraction and processing. [3] [4] This approach aligns with the principles of green chemistry, which aim to reduce or eliminate the use and generation of hazardous substances in chemical processes.

  5. Green solvent - Wikipedia

    en.wikipedia.org/wiki/Green_solvent

    Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future. [ 1 ]

  6. Nanochemistry - Wikipedia

    en.wikipedia.org/wiki/Nanochemistry

    Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...

  7. Green chemistry metrics - Wikipedia

    en.wikipedia.org/wiki/Green_chemistry_metrics

    The first general metric for green chemistry remains one of the most flexible and popular ones. Roger A. Sheldon’s environmental factor (E-factor) can be made as complex and thorough or as simple as desired and useful. [10] The E-factor of a process is the ratio of the mass of waste per mass of product:

  8. Green hydrogen - Wikipedia

    en.wikipedia.org/wiki/Green_hydrogen

    Hydrogen can be produced from water by electrolysis.Electrolysis powered by renewable energy is carbon neutral.The business consortium Hydrogen Council said that, as of December 2023, manufacturers are preparing for a green hydrogen expansion by building out the electrolyzer pipeline by 35 percent to meet the needs of more than 1,400 announced projects.

  9. Industrial Green Chemistry World - Wikipedia

    en.wikipedia.org/wiki/Industrial_Green_Chemistry...

    Industrial Green Chemistry World (IGCW), previously known as Industrial Green Chemistry Workshop [1], is the first and largest Industrial convention which focuses on expanding, implementing and commercializing green chemistry and green engineering based technologies and products in the chemical industry.
