1. Scientists at the Mumbai-based Tata Institute of Fundamental Research (TIFR) used gold nanoparticles and by rearranging size and gaps between them developed a new material.
2. Gold does not have these properties, therefore ‘black gold’ is being called a new material. In appearance it is black, hence the name ‘black gold.’
3. One of the most fascinating properties of the new material is its ability to absorb the entire visible and near-infrared region of solar light.
4. Black gold could also act as a catalyst and could convert carbon dioxide into methane at atmospheric pressure and temperature using solar energy.
5. The material can also be used as a nano-heater to covert seawater into potable water via steam generation using solar energy.
