Abstract: A sand aggregate includes plural aggregate grains, wherein at least one aggregate grain of the plural aggregate grains includes, desert sand grains that are too small to be used in concrete applications, carbonate particles distributed on an external surface of the desert sand grains, and a sand-based glue that aggregates the desert sand grains together. The at least one aggregate grain has a size comparable to river sand grains, while the desert sand grains have a size smaller than the river sand grains so that the at least one aggregate grain is suitable for concrete applications.

Abstract: Embodiments of the present disclosure describe pre-catalysts comprising including one or more of indium oxide, indium hydroxide, indium oxyhydroxide, an active oxide, and a refractory oxide. Embodiments of the present disclosure also describe method of making pre-catalysts based on one or more of impregnation, precipitation or co-precipitation, ball milling, and metal-organic framework (MOF)-mediated synthesis. Embodiments of the present disclosure further describe methods of activating pre-catalysts and synthesizing one or more of methanol and olefins using catalysts obtained from the pre-catalysts.
