In　this　study　the　production　of　high　surface　area　silver　nanoparticles　(AgNPs)　are　reported　from　the　Dodonaea　viscosa　plant　species　under　controlled　condition.　The　reaction　was　completed　at　40　°C　within　5　h　and　the　product　was　characterized　by　several　advanced　techniques　such　as　PXRD,　FTIR,　TGA,　FESEM,　XPS,　DRS,　BET,　and　UV–Vis.　The　prepared　AgNPs　were　also　evaluated　for　antimicrobial　activities　against　pathogenic　bacteria　and　fungi　such　as　multi-drug　resistant　Staphylococcus　aureus　(MRSA)　and　Candida　albican　at　a　minimum　inhibitory　concentration　(1　μg/mL)　with　9　mL　of　liquid　medium　(Nutrient　Broth).　AgNPs　were　also　found　to　speed　up　the　reduction　of　organic　pollutants　such　as　2-nitrophenol　(2-NP),　4-nitrophenol　(4-NP)　and　azo　dyes　included　Methyl　orange　(MO),　Congo　red　(CR)　and　Rhodamine　B　(RB)　which　causes　pollution.　The　highest　surface　area　is　found　for　Ag-25　(7.38　m2/g)　as　compared　to　others　NPs　might　be　the　highest　catalytic　potential　of　Ag-25.　©　2020　Elsevier　B.V.
