Efficient solar-driven CO₂-to-fuel conversion via Ni/MgAlO _x @SiO₂ nanocomposites at low temperature.

ABSTRACT: Solar-driven CO₂-to-fuel conversion assisted by another major greenhouse gas CH₄ is promising to concurrently tackle energy shortage and global warming problems. However, current techniques still suffer from drawbacks of low efficiency, poor stability, and low selectivity. Here, a novel nanocomposite composed of interconnected Ni/MgAlO _x nanoflakes grown on SiO₂ particles with excellent spatial confinement of active sites is proposed for direct solar-driven CO₂-to-fuel conversion. An ultrahigh light-to-fuel efficiency up to 35.7%, high production rates of H₂ (136.6 mmol min^-1g^{- 1}) and CO (148.2 mmol min^-1g^-1), excellent selectivity (H₂/CO ratio of 0.92)
