Artificial trees with leaves made out of a new discovered material ‘black gold’ can perform artificial photosynthesis, capturing carbon dioxide and converting it into fuel and other useful chemicals.

- Indian Scientists used gold nanoparticles and by rearranging size and gaps between them developed a new material which has unique properties such as capacity to absorb light and carbon dioxide.
- The scientists are from Mumbai-based Tata Institute of Fundamental Research (TIFR).
- Although Gold does not have these properties; and the appearance of new material is black, hence the name ‘black gold.’
- The new material was prepared by varying in inter-particle distance between gold nanoparticles using a cycle-by-cycle growth approach.
- It is able to absorb the entire visible and near-infrared region of solar light.
- It could also act as a catalyst and could convert carbon dioxide into methane at atmospheric pressure and temperature using solar energy. From this, it could be possible to covert carbon dioxide into fuel.
- It is also able to harvest solar energy. The material can be used as a Nano-heater to covert seawater into potable water with good efficiency.
