“…The pH of the mixed solution of the metal and precipitant was adjusted to 9, after which the temperature of the solution was maintained at 80 ℃ for 5 h while stirring at 600 rpm to form a precipitate. When synthesizing the catalyst by a co-precipitation reaction, a precipitate is formed according to Equation (2).…”

“…Energy demand has continuously increased with economic growth and advances in science and technology, and most of the world's energy is currently contributed by the burning of fossil fuels [1,2]. Excessive dependence on fossil fuels and depletion of petroleum reserves have raised concerns regarding energy shortages, and the concentration of greenhouse gases (GHGs) emitted from burning fossil fuels has rapidly increased, exacerbating global warming [3].…”

Catalytic decomposition of methane (CDM) is an environmentally friendly technique to produce hydrogen and nano-carbon materials without greenhouse gas emissions. To compare the catalytic activity and hydrogen productivity of various active metals in the CDM reaction, experiments were performed by synthesizing Fe–Al, Co–Al, and Ni–Al catalysts through the co-precipitation method. According to the hydrogen production calculation for each catalyst, the Ni-based catalyst exhibited the best hydrogen production at a reaction temperature of 600 ℃. It could be attributed to the influence of the strong metal–support interaction on the catalytic activity. Based on the Ni–Al catalyst, which showed better hydrogen production than the other active metals, the activity and hydrogen production of the CDM process were analyzed according to different process factors. 90 L/gcat of hydrogen was produced through the optimization of process factors such as reduction temperature, reduction time, spatial velocity, methane flow, and gas addition.
