Morphology-controlled synthesis of 3D flower-like TiO2 and the superior performance for selective catalytic reduction of NOx with NH3

NOx Removal by Selective Catalytic Reduction with Ammonia over a Hydrotalcite-Derived NiFe Mixed Oxide

“…During the past few decades, stringent regulations on NO x emissions have been issued worldwide and various measures have been devoted to diminish NO x , among which the removal of NO x from stationary sources by selective catalytic reduction of NO x with NH 3 (NH 3 -SCR) has been attracting significant attention due to the low cost and high efficiency [2][3][4]. The most adopted SCR catalysts in practical applications are V-based catalysts, while the toxicity of active vanadium species, together with high N 2 O formation at high temperatures, restricts their further application [5]. Therefore, for the current situation, developing environmentally friendly substitutive catalysts with excellent efficiency, strong stability, and high SO 2 resistance in NH 3 -SCR is imperative.…”

From metal–organic framework to morphology- and size-controlled 3D mesoporous Cr2O3 toward a high surface area and enhanced volatile organic compound oxidation catalyst

“…The design and synthesis of metal oxides with different sizes and shapes have stimulated great research interest, since the chemical and physical properties of the materials depend not only on their composition but also on their structures, sizes and morphologies. [13][14][15][16][17][18] Furthermore, it is well known that high surface area of materials could improve their surface performances, but there are rare 3D porous Cr 2 O 3 reported in previous works with specic surface area larger than 200 m 2 g À1 (most of them near 100 m 2 g À1 ), which greatly limits the performance and applications of the porous Cr 2 O 3 . Thus, methods to synthesize 3D porous Cr 2 O 3 with high specic surface area, shape control, high yields, low cost and good reproducibility are desirable.…”
