Photochemical hydrogen generation with porphyrin-based systems

Visible light-driven photophysics and photochemistry of water-soluble metalloporphyrins

“…Their advantageous photoinduced properties can also be exploited in various photocatalytic procedures [3,4]. Water-soluble derivatives can be utilized in environmentally benign systems not containing organic solvents.…”

ZnTPPS demetalation: Role of polyelectrolytes on aggregation after protonation in acid

“…PLL, in fact, is positively charged at pH = 1.5 and strongly attracts anionic porphyrins. The immobilization of H 4 TPPS 2-molecules through negatively charged SO 3 -groups catalyzes the attachment of other porphyrin molecules since their negative charge is partially diluted by the cationic nature of template.…”

“…Nowadays porphyrins find applications in many research fields from sensing [1,2] to photocatalysis [3,4] to biology [5][6][7], since they represent a versatile macromolecular platform characterized by an extensive electronic delocalization leading to intriguing optical and electronic properties. Among them, the high molar extinction coefficient allows use of extremely dilute solutions (< mM), a fundamental aspect in the perspective of the use of porphyrins as molecular probe to study interactions with biological and inorganic species.…”

A Recycling Hydrogen Supply System of NaBH4 Based on a Facile Regeneration Process: A Review

“…Hydrogen [1][2][3] has been widely accepted as a clear energy carrier [4][5][6] due to its high energy density (142 MJ/kg) [7][8][9] and its environmentally friendly byproduct (water) [10,11]. It can be generated via numerous strategies, such as the electrolysis of water [12][13][14] and photocatalytic water splitting [15][16][17][18].…”
