For many years, researchers have been focused on developing technologies that can help us fight the imminent climate change crisis. They have one goal in common: finding sustainable energy sources that can replace the environmentally toxic fossil fuels. "Photocatalysts" that drive an artificial process that replicates photosynthesis (in which solar energy is converted to useful materials) are promising in this regard, given that we are able to develop the technology needed for them. Crystalline materials, such as strontium titanate (SrTiO3), which can serve as "photocatalysts" in solar devices, can lead us in the direction.
