Abstract

ABSTRACT A cobalt-silica hybrid nanocatalyst bearing small cobalt particles of diameter ~5 nm was prepared through a hydrothermal reaction and hydrogen reduction. The resulting material showed very high CO conversion (>82%) and high hydrocarbon productivity (~1.0 gHC·g−1 cat·h−1) with high activity (~8.5 × 10−5 molCO·g−1 Co·s−1) in the Fischer–Tropsch synthesis reaction.
