Traditionally employed in alloy corrosion studies, dealloying has evolved into a versatile technique for fabricating advanced porous materials. The unique architecture of interconnected pore channels and continuous metal ligaments endows dealloyed materials with high surface-to-volume ratio, excellent electron conductivity, efficient mass transport remarkable catalytic activity, positioning them at the forefront nanomaterial applications significant potential. However, reproducible synthesis these structures remains challenging due to limitations conventional techniques. Herein, this review attempts consolidate recent progress electrochemical chemical methods nanoporous anodes energy storage conversion applications. We begin by elucidating fundamental mechanisms driving evaluate key factors influencing conditions. Through current research, we identify critical properties that warrant further investigation. Applications as metal-ion batteries, supercapacitors, water splitting photocatalyst are discussed. Lastly, address ongoing challenges field propose perspectives on promising research directions. This aims inspire new pathways foster development sustainable technologies.

Natural zeolite faces challenges in wastewater treatment due to poor mechanical stability, handling difficulties, and limited reusability. To address these limitations, structured is fabricated using 3D printing, with glycerol as a porogenic agent enhance porosity adsorption capacity. Scanning electron microscope–energy dispersive X‐ray spectroscopy confirms successful fabrication improves pore formation, while thermogravimetric/differential thermal analysis demonstrates stable properties. The pHpzc values are 7.43 (3D‐Ze/Gy50) 7.52 (3D‐Ze/Gy0), indicating minor surface charge changes after incorporation. Adsorption follows pseudo‐second‐order kinetic model (chemisorption) aligned the Langmuir isotherm, confirming monolayer on homogeneous surface. Thermodynamic reveals that process endothermic nonspontaneous at lower temperatures but becomes favorable higher temperatures. 3D‐Ze/Gy50 sample exhibits superior capacities of 1.35 mg g −1 15 L 2.04 25 Methylene blue concentrations outperform unmodified samples. Reusability tests show consistent performance over six cycles, regeneration achieved via resintering 600 °C for 2 h. These results validate potential 3D‐printed glycerol‐modified reusable, high‐performance adsorbent treatment, offering an innovative approach developing sustainable materials environmental remediation.
