“…[1][2][3][4][5] In the H-CPPs, such as, covalent triazine frameworks (CTFs), [6][7][8][9][10][11][12] conjugated covalent organic frameworks (COFs), [13][14][15][16] conjugated microporous polymer (CMPs), [17][18][19][20][21][22][23] or porous aromatic frameworks (PAFs), [24][25][26] versatile heteroaromatic structures can be incorporated into the polymer backbone or the linkages. These heteroatoms play essential roles in the photocatalysis and ion transport applications, because the heteroatoms in the H-CPPs can be active sites for the adsorption of gas molecules or ions in the catalysis and ionic conduction process, [27][28][29] stabilize the metal nanoparticles in heterogeneous catalysis, [30][31][32][33] or regulate band structures in the photocatalysis applications. [34][35][36] More specifically, the nitrogen-containing CPPs (N-CPPs) with high stabilities and excellent electronic properties have be incorporated with abundant heteroatoms.…”

An efficient and sustainable Pd‐nanomagnetic heterogeneous catalyst for the reduction of nitroarene and environmental pollutant

“…The aromatic amines are the most important starting and intermediate materials, which are utilized in various industries like pharma, dyes, chemicals, explosives, polymers, fertilizer, and rubber industries. 8,16,[34][35][36][37] The two prevalent methods for producing amines include reacting functional groups such as I, Br, Cl, F, OH, and H with diazonium salts and using homogeneous catalysts to reduce nitro compounds through hydrogenation. 35,37 The existing viable approaches often need high temperatures and pressure and long response times, which are not economical.…”

“…[39][40][41][42][43][44] At present, researchers have developed a range of nanocatalysts utilizing noble metals to reduce nitro compounds, such as Pd, Pt, Au, and Ru. 36 A family of noble metal catalysts known as Pd has a distinctive structure and several uses. 33,[45][46][47][48][49][50] Over time, various palladium-based catalytic materials have been created to attain high catalytic potential to reduce nitro compounds.…”

“…33,[45][46][47][48][49][50] Over time, various palladium-based catalytic materials have been created to attain high catalytic potential to reduce nitro compounds. 8,[34][35][36][37][51][52][53][54][55] Heavy metal contamination of water is a major ecological concern, especially in industrial wastewater, where Cr(VI) is a major pollutant. [56][57][58] As per consensus, it is the second-most prevalent heavy metal contaminant in hazardous waste sites.…”
