Summary: In this study, highly active methane dry reforming (DRM) catalysts with superior coke-resistance were obtained by employing a nanocasting method to synthesize mesoporous La2O3 support using KIT-6 as a hard-template. The La2O3-KIT-6 support exhibited a high specific surface area and well-formed mesoporous structure, leading to a highly dispersed Ni active sites and enlarged interfaces between La2O2CO3 and Ni. This facilitated the reaction between coke and La2O2CO3 species, keeping the Ni sites more clean and active.

Summary: Dry reforming of methane (DRM) is a green alternative for utilizing greenhouse gases and producing syngas. The main limitations of DRM are catalyst sintering and coking. Recent studies have focused on Ni-based catalysts for DRM due to economic constraints on noble metal-based catalysts. Mesoporous silica (MS) supported catalysts show promise due to their high surface areas, thermal stability, and easy availability. However, research on MS as a catalyst support for DRM is still limited.

Summary: This study investigates the catalytic properties of various monometallic Ni catalysts in the oxy-steam reforming of LNG for the first time. Various research techniques were used to study their physicochemical properties, and the high activity of monometallic catalysts on 5% La2O3-CeO2 and 5% ZrO2-CeO2 in the process was attributed to acidity, specific surface area, sorption properties, crystallite size, and phase composition.
