These systems combine the advantages of homogeneous catalysts, such as high activity and selectivity, with those of solid supports, including enhanced recyclability. Catalytic hydrogen (H\n                    <jats:sub>2<\/jats:sub>\n                    ) production via dehydrogenation of C1 organic molecules targeting its use in fuel cells is a contemporary scientific issue directly connected with climate crisis. Here, Iminophospine hybrid [SiO\n                    <jats:sub>2<\/jats:sub>\n                    @benzNP] and its reduced analogue [SiO\n                    <jats:sub>2<\/jats:sub>\n                    @benzNHP] were synthesized, covalently grafted on colloidal SiO\n                    <jats:sub>2<\/jats:sub>\n                    , fully characterized (FT\u2010IR, RAMAN, TGA, ssNMR, BET), and used for\n                    <jats:italic>in\u2010situ<\/jats:italic>\n                    synthesis of [SiO\n                    <jats:sub>2<\/jats:sub>\n                    @benzNP\u2010Fe\n                    <jats:sup>II<\/jats:sup>\n                    ] and [SiO\n                    <jats:sub>2<\/jats:sub>\n                    @benzNHP\u2010Fe\n                    <jats:sup>II<\/jats:sup>\n                    ] catalytic complexes for H\n                    <jats:sub>2<\/jats:sub>\n                    production from formic acid (HCOOH) and formaldehyde (HCHO), at 80\u2009\u00b0C. In HCOOH, both heterogenized catalysts exhibit high selectivity, producing H\n                    <jats:sub>2<\/jats:sub>\n                    and CO\n                    <jats:sub>2<\/jats:sub>\n                    in a 1\u2009:\u20091 ratio, without CO contamination, making them ideal for fuel cell applications.

In HCOOH dehydrogenation, over 82,000 turnover number (TONs) were achieved and retained its efficiency for over five cycles, without any further metal addition. In HCHO dehydrogenation, it showed excellent efficiency as well, achieving 1.3\u2005L of pure H\n                    <jats:sub>2<\/jats:sub>\n                    with TONs exceeding 7,000, in 3 consecutive uses. Advanced spectroscopic analysis confirmed the stability and structural integrity of the catalysts, linking the Schiff base reduction and N\u2212H groups to enhanced activity, durability and reusability.
