- Abstract
- Ammonia-based selective catalytic reduction (NH₃-SCR) stands as the preeminent strategy for NOx mitigation in industrial flue gases. Nonetheless, incumbent V₂O₅–WO₃/TiO₂ catalysts are beset by constrained temperature operability, toxicity concerns, inadequate hydrothermal endurance, and susceptibility to SO₂/H₂O deactivation. Contemporary investigations have converged on advanced structural modulation—encompassing dimensionality, morphology, and pore hierarchy—to augment active-site utilization, acid-base equilibrium, and mass/electron conveyance. Diverging from recent reviews that predominantly address material-centric themes (e.g., Cu-based zeolites or core-shell motifs) or isolated attributes, this contribution furnishes a holistic, multiscale amalgamation of advancements in dimensional modulation (1D nanowires, 2D nanosheets, 3D scaffolds), morphological constructs (rod-like, laminar, core-shell, yolk-shell, hollow configurations), and hierarchical porosity (micro-meso-macro integration). We delineate core mechanisms, including pore-caliber-mediated molecular sieving, steric impediments, diffusion orchestration, and confinement-driven phenomena such as reactant sequestration, oriented translocation, and amplified adsorption-redox sequences. Merging these elements with state-of-the-art in situ/operando spectroscopic elucidations, we extrapolate pragmatic design tenets for low- to medium-temperature deNOx catalysts that harmonize exceptional efficacy, longevity, and antitoxin fortitude. This synoptic vista not only expedites the conception of resilient industrial deNOx architectures but also proffers a adaptable schema for structure-property refinement in heterogeneous catalysis writ large.
